Manchester United loanee Marcus Rashford only makes the bench for a Barcelona team featuring star names like Lamine Yamal and Robert Lewanowski.
Chelsea XI: Sanchez; Gusto, W Fofana, Chalobah, Cucurella; Caicedo, James; Estevao, Fernandez, Garnacho; Neto.

There will also be a Champions League Match of the Day on BBC One on Wednesday, from 22:40 to 00:00.
Image source, Getty ImagesCole Palmer will be a "huge miss" for Chelsea when they face Barcelona, but they still have the "resources to be competitive" without him, says former forward Gianfranco Zola.
Palmer is set to miss the Champions League match at Stamford Bridge on Tuesday night with a fractured toe, despite wearing a specially adapted boot to help him in training.
The 23-year-old had already been recovering from a groin injury that has kept him out since September.
Despite this, the Blues have been on a good run of recent form with no defeats in their past five games across all competitions.
"He [Palmer] is a huge miss. We know that Cole is such an influential player for the team," Zola told BBC Radio 5 Live.
"But the squad Chelsea have got, they are very competitive. They have young players coming though – Estevao is one those – so they have the resources to be competitive without Cole.
"Of course when Cole is back it will be a team with a different dimension."
Chelsea boss Enzo Maresca will be coming up against a side in Barcelona that inspired his own managerial style when Pep Guardiola was in charge, but Zola feels this will make for a interesting match-up.
"It will be one of the key points [Maresca's Guardiola inspiration], but Maresca has also proven he has his own way to play," he added.
"I really like it because, despite being a team that likes to create a lot of chances offensively, in my opinion it is very balanced. It is a team that also defends well.
"It will be interesting because on the other side Barcelona go on the front foot in every game."

On the latest episode of BBC Radio 5 Live's Monday Night Club, the panel discuss Chelsea's Champions League game against Barcelona.
The Observer's Rory Smith says that there is an "element of phoney war" around the match. Given both teams will likely progress to the knockout stages regardless of the result, he says the game "ultimately, doesn't matter".
Former Premier League goalkeeper Joe Hart, says Tuesday's match will be helpful for Chelsea to "work out who they are" against one of the biggest teams in Europe.

Image source, Getty ImagesEvery exciting young attacker is rated on a scale from one to Lionel Messi.
The two teenagers perhaps at the upper end of the scale are Lamine Yamal - already a global superstar - and now Chelsea's Estevao Willian.
Yamal, like Argentina legend Messi, emerged from Barcelona's famed La Masia academy.
Estevao was reluctantly crowned 'Messinho' - translated as 'little Messi' - through his performances in Brazil's top flight, and has started brilliantly since joining Chelsea after the summer Club World Cup. He moved after his 18th birthday, having agreed a pre-contract in May 2024 to join from Palmeiras for £29m, rising to £51m with add-ons.
They are now considered the two most valuable teenagers in world football - according to CIES Football Observatory,, external Yamal is valued at a staggering £307.4m, with Estevao second but lagging far behind at £103.8m.
One of the few people capable of comparing the two forwards is Chelsea defender Marc Cucurella.
Cucurella said: "I think both of them are very special players. They have a lot of talent, always want the ball, and take on defenders one-on-one. They are players who can decide games."

Image source, Getty ImagesOnce again there were groans about players coming back from all over the world to play in the Premier League. I agree with Enzo Maresco that Chelsea's early kick-off at Burnley was a tough ask for many of them, though I can't bring myself to entirely blame those who decide on the fixture timings.
Are clubs still unaware that when they buy players from different continents this is likely to happen? Surely this must be factored into the decisions to buy.
If not, it is either staggering ignorance or astounding arrogance that they think club football is always more important than the international game.
Maybe some clubs do think that way. After all, they might argue that they pay the wages. But that that attitude must be challenged because of the importance and history of international football, especially with a World Cup looming.

Image source, Getty ImagesChelsea's win over Burnley was achieved without Moises Caicedo or Cole Palmer having to play a minute, something we have not seen too often in the past couple of seasons.
Without the injured Palmer, the team have had to scratch around for goals and rely on Caicedo's phenomenal form to help them create their own chances as well as to prevent the opposition doing the same.
On the rare occasion they have tried to leave the Ecuador midfielder out of the line-up, they have been forced to bring him on post-haste once it became clear how helpless the team were without him.
Even in this game, as the first half wore on, it felt like things might be going that way. It was a slow start from the Blues and they lacked any control in the middle. Plenty of fans and pundits would have been wondering how long Enzo Maresca could last without turning to his main midfield dynamo.
Fortunately for Chelsea - and for Caicedo's legs - it wasn't necessary. A lovely goal out of nowhere put the Blues ahead and forced Burnley to open up. It was still tense through the second half, until Maresca's team once again struck just as things were about to get really worrying and sealed the win.
It was a game where they just needed to get the job done, and they did that in the end. Andrey Santos played the game as Caicedo's understudy and, while the team weren't totally convincing, he did his bit in attack and in defence to make up for the key man's absence.
With three important points in the bag, all attention turns now to this week's more important tests against Barcelona and Arsenal. Eighteen months into Maresca's reign, we will find out how good this team really are.

Image source, Getty ImagesChelsea defender Marc Cucurella says it is "always difficult" to play against "special talents" like team-mate Estevao Willian and Barcelona's Lamine Yamal.
The two young stars could face each other on Tuesday when the Blues host Barcelona at Stamford Bridge in the Champions League.
It is likely Spain full-back Cucurella will be in direct opposition to compatriot Yamal on Tuesday evening with the 18-year-old boasting four goals and three assists in his past four appearances for Barcelona.
Asked whether training with Estevao could help his preparation to take on Yamal, Cucurella joked: "I tell [Estevao] to put shin pads on in training because I start the training with him."
He added: "But no, it's difficult. These kind of players are always difficult to play against because they have a special talent, a lot of quality.
"Tomorrow I think is not Yamal vs Cucurella - it's a big game.
"My team-mates will try to help me and we need to have a big game because we want to win. It's a tough battle, but hopefully we can do our best and win the match."
Despite having his playing time managed by Chelsea boss Enzo Maresca, summer arrival Estevao has lit up the field when brought on, most notably scoring a stoppage-time winner against Liverpool in the Premier League.
He may be new to English football but Estevao already has five goals in just 11 appearances for his national side Brazil and is drawing comparisons with Ballon d'Or runner-up Yamal.
"I think both of them are really very special players," Cucurella said. "They have a lot of talent. They always want the ball. They always try to do one on ones. They are players [that] can decide games.
"I think the only difference at the moment is Lamine has been playing in Europe for two or three seasons and Estevao is arriving this season - but he [Estevao] is doing really well.
"If he continues in this way, at this level and improving in all aspects, he can arrive to the Lamine Yamal level."
Nicola Pearson
BBC Sport journalist
Chelsea boss Enzo Maresca has been speaking to the media before Tuesday's Champions League game against Barcelona at Stamford Bridge (kick-off 20:00 GMT).
Here are the key lines from his news conference:
Maresca confirmed that Cole Palmer, who has a specially adapted boot to protect his fractured toe, will be back "soon" as he is "already touching the ball and the feeling is good". However, Maresca does not feel at the moment his playmaker will be ready to face Arsenal at the weekend.
The Blues boss acknowledged this is a "big week" for Chelsea, but with games coming up away from home against Leeds, Bournemouth and Atalanta then it is "always a big week" and "always important games". He added: "Games like Barcelona and Arsenal are important for different reasons, but I think the best thing for us is to go game by game."
On comparisons for Estevao Willian with Lamine Yamal and whether he should embrace it or shut it out: "Estevao is already playing at a high level, starting already with Brazil. He is very young, for sure he can do many things better, but we are very happy with him."
He continued: "For me, it's more or less the same thing I said about Pedri. It is nice for people who love football to watch players like Estevao, Lamine Yamal and Pedri - this is the beauty of the football. We are happy Estevao is with us and for sure, he is going to do well."
On whether Estevao can be as influential for Chelsea as Yamal is for Barcelona: "He can be. He is going to be an important player for this club, no doubt. The most important thing for Estevao is that he has to enjoy football, he has to be happy, and not think about being better than this player or another player. Only think about himself and try to be better, working hard day by day."
Asked about stopping striker Robert Lewandowski, Maresca insisted they will "as always, try and defend as a team" and be "aggressive in the way we try to defend".
He accepted the threat Barcelona will pose, but highlighted his own side's abilities: "They have so many players [who can score], but at the same time we have so many players that can try to win the game."
On if teams can still win the biggest trophies playing in the Barcelona style of the past that inspired him: "I don't know. I decided to be a manager because of Pep's [Guardiola] Barcelona team years ago. I have said many times any club and team can decide their way to play. I chose mine years ago, that this would be the way I like to watch my team playing football."

Chelsea reporter at Stamford Bridge
Image source, Getty ImagesChelsea normally hold their major news conferences for big Champions League matches at Stamford Bridge rather than at their training ground.
There is no doubt that Chelsea's home supporters were most excited about drawing Barcelona – a team with whom they have built a rivalry – on their return to the Champions League this season.
Barcelona are also the club that inspired Maresca to go into management, after he was blown away by facing a Pep Guardiola-led side while playing for Sevilla in Spain's top flight.
The tiki-taka style that Guardiola pioneered is one whose legacy Maresca is continuing today.
It will be interesting to hear Maresca retell those stories, discuss Cole Palmer's fitness situation, and perhaps assess where Estevao Willian is in comparison with visiting teenage superstar Lamine Yamal.

We asked for your thoughts after Saturday's Premier League game between Burnley and Chelsea.
Here are some of your comments:
Burnley fans
Paul: Very poor. Chelsea were the worst team at Turf Moor all season after the Clarets. There for the taking, but Burnley had nothing. Scott Parker out.
Michael: Terrible. Got to start a front man. Maybe it is time for Armando Broja to step up or it is back to the Championship.
Shaun: Absolutely rubbish - no communication and no team spirit. Chelsea destroyed them and deserved the win.
Dougie: Pleased to note that Turf Moor has a Jimmy McIlroy stand. Outstanding player saw him a few times in Belfast playing for Northern Ireland. Wasn't a player on either side in this game fit to lace his boots.
Chelsea fans
John: Bang average against a relegation candidate, but a win is a win. We will have to improve to win our next few games against better opponents.
Scott: Yet again, Enzo Maresca's in-game management could easily have cost us this game with substitutions that invited pressure. It was only moments of player quality that got us the three points, and the fact that Burnley are very poor.
Julian: For quite a bit of the game, it seemed many of Chelsea's players were suffering from an international hangover. However, that second goal gets better every time I watch it. Three points in what could have been a banana skin of a fixture.
Chris: Another average performance to overcome Burnley. Marc Cucurella was brilliant again, but why does Maresca insist on playing Liam Delap ahead of MArc Guiu? He seems to have his 'favourites' who play whenever, and we can't afford that attitude. We will see how good we are, or how good Maresca thinks we are, next Sunday against Arsenal.

Image source, Getty ImagesChelsea midfielder Andrey Santos says his display against Burnley was his best Premier League performance for the club ahead of a crucial week.
The 21-year-old completed his first full 90 minutes in the competition during Saturday's 2-0 win at Turf Moor.
Previously, Santos had been substituted at half-time and after 54 minutes in his other two league starts.
Asked about his performance — in which he was named man of the match while playing a deep midfield role as Moises Caicedo was rested — Santos said: "Yes, of course, I think today is my best performance.
"I think the adaptation is a little bit hard because the Premier League is the toughest championship in the world.
"But now my teammates have helped me a lot. I'm so happy to be here in the Premier League."
Chelsea moved up to second in the Premier League ahead of a week that sees them face Barcelona in the Champions League on Tuesday, followed by Arsenal in the league next Sunday.
Santos added: "Yes, of course. When you talk about the Champions League, it's always amazing. I always dream of these big games. Now we have Barcelona, and we hope we are ready to fight and try to win the game.
"Barcelona first and then Arsenal. It's a great week. We are Chelsea — we work hard and want to win every game."

Image source, Getty ImagesReece James hugged Jamie Gittens after the 2-0 win at Burnley
Chelsea manager Enzo Maresca has calmed fears that Reece James was injured during the 2-0 win at Burnley on Saturday afternoon.
The Blues captain came off at half-time and was replaced by fellow defender Benoît Badiashile, as goals from Pedro Neto and Enzo Fernandez secured victory for the Londoners at Turf Moor.
Maresca explained the switch after the match that it was a premeditated substitution.
"Yes, the idea was to manage Reece [James]. This is the reason why he played 45 minutes – it was planned."
The rotation and rest for key players in a dominant victory seemed like perfect preparation for a week in which Chelsea welcomes Barcelona and Arsenal to Stamford Bridge in the Champions League and Premier League.
Maresca, marking his 50th league match as Chelsea manager, left star midfielder Moises Caicedo on the bench throughout and was pleased his deputy, Andrey Santos – who won man of the match – shone in his absence.
"Andrey's position is the position he played today," Maresca added. "With us, most of the time he plays a little higher because in that position we have Moises, so we try to find solutions and space for Andrey."
Nizaar Kinsella
Football reporter
Image source, Getty ImagesChelsea defender Marc Cucurella was outstanding in both defensive and attacking moments, inspiring the breakthrough goal.
The Blues were not at their best against Burnley at Turf Moor, but his unlikely run into a striker's position helped Neto break the deadlock.
Roaming from his usual left-back role, Cucurella found himself in a number nine position, brought the ball down like a target man and laid it off for Gittens to cross for Neto's header.
That clever movement proved impossible to track, and a subsequent run into midfield created a chance for Liam Delap, which he squandered. Delap now has only one goal in 13 matches since joining Chelsea.
Cucurella repeated that same movement into a striker's position twice in the second half, mounting a further blocked shot and producing a similar lay-off to a team-mate.
There is no doubt Cucurella was Chelsea's star on the day, and he is in the conversation alongside Cole Palmer and Caicedo as one of the club's very best players.
Maresca happy to win 'complicated' game
Chelsea manager Enzo Maresca to BBC Match of the Day: "I'm very happy, this kind of win, we needed it. After the international break, 12:30, Burnley away, it's complicated. So I'm very happy with the result and the performance.
"They defended very well and didn't give us many spaces to attack. It was complicated. I think it's complicated to come here and don't concede. They only add one big chance in the second half, if you ask me. Overall, we created more chances and deserved to win.
"I'm very happy with the goal. The ball from Jamie Gittens was very good, and Pedro Neto got to score. I am very happy for them."
On Andrey Santos' performance: "Andrey's position is number six. With us, he is also playing in other positions, which is not his best. But he's a good boy and works hard. We are happy."
On Reece James being substituted at half-time: "Yes, it was planned for 45 minutes."
Chelsea's Jamie Gittens speaking to BBC Match of the Day: "It was a hard-fought win to come to Burnley and get three points, is good for us. We feel more confident.
"We expected it to be a really tough game and fighting for the second balls, and we did really well today. To come back and play at 12:30 on Saturday is not easy, and I am happy we got the win."
On his assist for Pedro Neto's goal: "I have been working on that in training, and it came off in the game. I am happy it came off. Pedro got there in the end.
"We are definitely more confident and more comfortable playing with each other. We are going to keep working hard as a team."
Did you know?
Chelsea have won each of their last eight Premier League games kicking off at 12:30 on a Saturday, with only Manchester City enjoying a longer run of successive victories in this specific kick-off slot in the competition (9 wins in a row from May 2021 to Oct 2022).
No manager has been shown more Premier League cards since the start of last season than Chelsea's Enzo Maresca (8 – level with Fabian Hurzeler).
