I think the lack of top quality in the Premier League is summed up by the previous use of the phrase 'the best league in the world' being replaced nowadays by 'the most entertaining league in the world'

Mr. Red, London

Do you know your best team?

Chelsea boss Jose Mourinho: "When you win matches, you perform well, it is easy to know your best team. 

"When the team is not winning on a regular basis it is normal that you have to make changes. After games like tonight it is difficult to analyse."

Porto 'spectacular'

Porto manager Julen Lopetegui: "The players' attitude was amazing, spectacular. It was our best performance of the season.

"I have to congratulate my team. This three points are totally deserved. It was tough and unfair to go to the dressing room at half-time with a draw, but we reacted well."

Wolves manager Kenny Jackett pays tribute to outgoing chairman, Steve Morgan after a 3-0 win at Wolves: "He has been great for me personally, and I wish him well for the future.

"I felt we were the better team even before the sending-off. We showed signs of recovery after an indifferent start."

Birmingham manager Gary Rowett: "We got back to our identity tonight after beating Brentford 2-0. We were solid and we dominated the second half."

Arsene Wenger again bemoans his side's 'bad luck' in defeat at home to Olympiakos. I can't see that washing with Arsenal fans...

Get Involved

Typical Arsenal. We've been hearing the same arguments about Arsenal for the past eight years. Wenger's too stubborn to address the weaknesses in the squad. They have never come close to replacing Campbell, Vieira, Gilberto and Henry. Lightweight players who cannot mix it up will get you nowhere.

Hoping Lewandowski is washing his hair on 20th October and 4th November...

Mourinho not overly critical

Chelsea boss Jose Mourinho: "The most basic thing in football is a defensive set-play. We had chances after that to get a positive result and we had a clear penalty - so for me I am not here to criticise the players.

"I am not going to point the finger but two mistakes cost us the game. The team played well against a difficult opponent. The Champions League brings a different atmosphere."

'Bad luck and lack of concentration'

Arsenal boss Arsene Wenger: "It is still possible of course to qualify but it is difficult to swallow losing a game like that. We lost it on a lack of defensive concentration and bad luck. They had four shots on goal and we conceded three goals.

"The turning point at 2-2 is we give them a goal again straight away. If it stays 2-2 for five minutes we win the game.

"A goalkeeper can make a mistake that doesn't explain that we lose the game. It happened to Petr Cech already this season [against West Ham]."

Ian Lamerton: Wenger has to take the blame. Disrespected Zagreb and Olympiakos with team selections and paid the price

Kaganzi Allan: Arsenal is not only pedestrian but primitive.They lack ideas where they are needed most!!

'A ridiculous goal'

Chelsea manager Jose Mourinho: "We watch dozens and dozens of repetitions of Porto taking corners. We were completely ready for that and in a moment when the game is under control we concede a goal that is ridiculous.

"They hit the post from a similar mistake. Apart from that the game was balanced. Two ridiculous moments and we were punished."

New manager, same results for Brentford.

Their 2-0 loss to Birmingham is their second home defeat in four days and they remain just a point ahead of the bottom three.

Blues meanwhile leapfrog Burnley and Cardiff into fifth place.

Wolves climb to 10th with their 3-0 win over 10-man Fulham. Tom Cairney's dismissal led to a one-sided game, with substitute Sheyi Ojo scoring one and making another before James Henry's free kick made it three.

Fulham drop to 14th.

It's a shambles at the Bridge, Mourhino should have gone after the saga with the doctor , he thinks he is bigger than the club. Well Jose you're not, you are arrogant, and you will be gone by Christmas. PS it could be worse, I could be an Arsenal fan

Phil in Melksham

For me, the Premier League is the best in the world for entertainment. Maybe the quality isn't there in Europe compared to the late 2000s and it isn't as competitive in major competitions as it once was. But that just adds to the drama and unpredictability of English clubs and the Premier League. Millions still tune in to the the league every week for this reason, and so may it continue.

"Chelsea didn't have a problem going forward but that's another two goals they've conceded tonight, and Asmir Begovic made some outstanding saves, too.

"The word from inside Chelsea on Baba Rahman is that he's a bit rash. Maybe tonight under the spotlight Jose Mourinho probably thought he couldn't leave out Branislav Ivanovic by moving Cesar Azpilicueta to the right.  

"In the second half Porto were all over them and Begovic was probably Chelsea's man of the match, but overall their performance wasn't bad."

Portsmouth's unbeaten run came to a surprising end at the hands of Exeter who won 2-1.

Crawley climb out of the bottom two with their convincing 3-0 win at bottom side Newport.

"If you are the Arsenal manager, you've just signed a goalkeeper, it’s the first time in a long time you've had a top goalkeeper, you've had David Seaman and Jens Lehmann, now you've got Petr Cech, you have to play him.

"Cech is the best keeper, and it was imperative they won at home tonight, with Bayern Munich coming up. To concede three goals at home to Olympiakos? Who have never won a competitive tie in England?"

Arsenal in trouble?

GOAL - Arsenal 0-1 Olympiakos

Reuters

Arsenal's ragged defence does cost them as the Greek side take the lead from the corner. It's pulled back deep to Felipe Pardo lurking on the edge of the area. He connects well, but the ball takes a huge detour off the backheel of Alex Oxlade-Chamberlain and into the far corner. 

Brown Ideye! Dear oh dear. Arsenal's centre-backs get in each other's way to give Brown a free hit on goal but he can't sort his feet out and is eventually crowded out. Corner.

Francis Edwards: Lucky enough to be at the Bayern v Zagreb game, how on earth did Arsenal lose to this team? Could be double figures tonight.

I think I know the answer to this one Frank. It's because Bayern are REALLY GOOD at football. Robert Lewandowski has just scored (again) to put Bayern 4-0 up now. That's his ninth goal in three games...

Lovely feet from Porto full-back Maxi Pereira to get a shot in which is deflected away. Pereira will be on the move to the Premier League or El Clasico soon enough. Most Porto defenders seem to eventually...

"Diego Costa is head and shoulders above everyone else on the pitch so far in this game. He's been far and away the best player."

Costa causing chaos

Plenty of touches for Chelsea striker Diego Costa but, so far, none inside the penalty area.

Elsewhere in Europe

Barcelona are behind! Kyriakos Papadopoulos has scored for Bayer Leverkusen (a real scrappy one at the near post from a corner) at the Nou Camp. Barca are without Lionel Messi, remember... Luis Suarez and Neymar to the rescue?

In the other game in Chelsea's group, Dynamo Kiev are leading Maccabi Tel Aviv 1-0, while in the other game in Arsenal's group, Bayern Munich are already 3-0 up at home to Dinamo Zagreb.

CLOSE!

Vincent Aboubakar pins his man with a ball into feet, he rolls the defender and shoots high and wide over the bar. Porto then think they should have a penalty - Branislav Ivanovic gets the ball but he does dive in a bit. 

Anyone get the feeling Olympiakos believe they can get at Arsenal down the flanks? As the graphic shows below, the Greeks have hardly gone down the middle as an attacking force.

Olympiakos have a rare foray forwards and Kostas Fortounis skims a left-footed strike wide from 20 yards.

YELLOW CARD

That is a nasty one. Bruno Martins Indi is late on Pedro as Chelsea counter, and he hammers the Spanish winger right on the top of the ankle. Could easily have injured Pedro, and the Dutch defender is booked.

Chelsea free-kick, and Diego Costa is back winding up defenders again. The referee steps in and WIllian hits the first defender. 

Bottom club Blackpool are winning 1-0 at home to Chesterfield after Mark Cullen scores in the second minute.

Hoping to make it four wins on the bounce, Colchester's Callum Harriott gives them the lead against Bradford.

Elsewhere, Rochdale have made it 3-0 against Shrewsbury and Fleetwood have taken a 1-0 lead away at Gillingham.

Arsenal are, as expected, posing more of the attacking threat. The graphic below shows the average position of the two sides and how Arsenal's centre backs may be a little bit quiet this evening.

Diego Costa looks back to his menacing best tonight. He's working very hard indeed up front for Chelsea.

Wide open at The Emirates - moments of anxiety for Arsenal while opportunities on the break for Alex Oxlade-Chamberlain and Theo Walcott at the other end. Olympiakos coach Marco Silva was so peturbed by one Arsenal counter that he indulged in a spectacular Basil Fawlty-style dance of fury in his technical area.

Elsewhere in Europe

BATE Borisov of Belarus (that's Borisov Automobile and Tractor Electronics for you and me) have taken a surprise lead at home to Roma - they're 2-0 up already!   

In the other game in Chelsea's group, Dynamo Kiev have taken an early lead at Maccabi Tel Aviv, while in the other game in Arsenal's group, Douglas Costa has scored to put Bayern Munich 1-0 up at home to Dinamo Zagreb.

GREAT SAVE!

What a pass! What a touch! Pedro's first touch is wonderful to tame a ball pinged into him, he can't quite get the ball out of his feet though and Iker Casillas is able to make the save with his feet.

Saint Iker indeed! Jose Mourinho is not happy, the Dragao is booming. Great noise. 

The game has come alive. Brown Ideye is close to steering in a free-kick from the right for Olympiakos but again Arsenal counter like a cornered snake, freeing Theo Walcott on the burst but his shot is poor. 

Mark Lawrenson

BBC Radio 5 live in the Estadio do Dragao

"It's a really lively game here, it's been a good start. Diego Costa is looking very, very sharp.

"Chelsea know they're going to be in a game but they also know they can cause problems on the counter attack. Porto do commit players forward."

CLOSE!

Olympiakos obviously didn't watch MOTD on Saturday as they are caught on the break just like Leicester were time and time again.

The Greek side have a corner, Hector Bellerin heads it out and Arsenal are go-go-go!

Alexis Sanchez frees Alex Oxlade-Chamberlain sprinting into the box, he shoots near post - side netting. Should go across the keeper!

Alexis Sanchez cuts in from the left and wants a free-kick as he takes a tumble but referee Bas Nijhuis says no. Olympiakos then counter for the first real time and former West Brom man Brown Ideye is close to reaching a ball over the top. 

GREAT SAVE!

Diego Costa down the left-hand channel, holds it up well, needs support - and has it. He pulls the ball back to Cesc Fabregas 20 yards out, foot through it but Iker Casillas watches it like a hawk and turns it away. Good game so far.

Alex Oxlade-Chamberlain gives it some gas down the right wing but Dimitris Siovas does well to track him and make the challenge. Arsenal look comfortable.

Lovely feet from Yacine Brahimi as he turns away from two Chelsea players in midfield and gets a shot off from 22 yards - straight at Asmir Begovic though. Pedro did well to get back and hassle him.

Porto starting well as Andre Andre almost gets in behind Gary Cahill.

Speaking the blindingly obvious

Barcelona forward Lionel Messi is impossible to replace, boss Luis Enrique said in the build up to tonight's game with Bayer Leverkusen.

Messi, 28, will be out for seven to eight weeks after tearing a ligament in his left knee during a 2-1 win over Las Palmas on Saturday.

"It's a challenge for us to be without the best player in the world," said Enrique on Monday.

"It also provides an incentive for us."

Messi scored 43 La Liga goals last season in addition to a further 10 in the Champions League as Barca were crowned champions of Europe.

The 28-year-old stands second - three behind Real Madrid forward Cristiano Ronaldo - in the list of all-time top scorers in European Cup history on 77 goals.

The changing face of Jose

Jose Mourinho has had many players, for many teams, over the past decade. But how do a select three sides match up?

BBC

His breakout Porto side of 2004 contained some key men who would follow Jose to Chelsea later that summer in right-back Paulo Ferreira and centre-half Ricardo Carvalho, while Deco would eventually play for the Blues too after a successful stint at Barca.

Maniche also had a spell with the London club.

BBC

This Chelsea side - in Jose's second season at Stamford Bridge - went out of the Champions League to Barcelona.

But was this his best team to watch? Arjen Robben and Damien Duff, Claude Makelele in the role he made his own, Frank Lampard and Didier Drogba weighing in with the goals..

It seems hard to comprehend now, but Jose Mourinho was a relatively unknown, young coach when he has handed the Porto job in January 2002.

Porto were fifth in the league, below Mourinho's then-side União de Leiria, out of the Champions League and out of the cup.

Within two-and-a-half years Mourinho guided Porto to two league titles, the Uefa Cup, and the Champions League.

An awesome achievement.

Who knew this fresh-faced young man was about to be the biggest coach in Europe?

The rest,as they say, is history.
