Will in-form Crystal Palace go for it in the FA Cup? I really hope so.
Oliver Glasner's side have improved as the season has gone on and they are comfortably in mid-table of the Premier League without any danger of going down. A cup run would really cap this as a successful campaign for him.
It would have an even bigger impact for Palace's fans. I still remember Ian Wright's goals in the 1990 final where they lost to Manchester United in a replay. They lost to United in the 2016 final too, and it would be great to give them a new memory.
This won't be easy, because former Norwich boss Alex Neil took charge of Millwall at the end of last year and is doing a good job.
They have been quite stubborn in recent weeks and I'm expecting more of the same here, but the Eagles should edge it in normal time.
Sutton's prediction: 2-1

Crystal Palace boss Oliver Glasner has been speaking to the media before Saturday's FA Cup fifth-round game against Millwall (kick-off 12:15 GMT).
Here are the key lines from his news conference:
On team news: "All players are fit and available. Marc Guehi is OK [after the win over Aston Villa]. It helped that we had one more day between these two games. The only change is Matheus Franca will be in the squad, and Caleb Kporha won't be, but all others are ready."
Glasner said he has "not decided" whether midfielder Adam Wharton, who made his first Premier League start since October on Tuesday after recovering from a long-term groin injury, will play: "We have to be smart and not say 'he had a great game, so he'll play again three days later.' He was injured for a very long time, then had 10 minutes at Fulham, and 80 minutes against Villa. It's the third game in seven days – so let's see. We have one more day."
On if Palace can win the FA Cup: "We have to show it tomorrow. That's why I don't talk about winning the FA Cup now when we are at the round of 16. We are facing a good Millwall side and they will try to take their chances. It makes no sense talking about winning a trophy when you are in the round of 16."
On preparing for their Championship visitors: "We will play with the best available team, with who's ready and fit. It's not about giving someone a gift – 'now you get some minutes because it's an FA Cup game' – this is disrespectful to Millwall. They can expect that we will play with our best team because this is what they deserve. They won at Leeds [in the fourth round], so that shows that they are able to win away against a good team. We have to be very focused and concentrated."
Glasner continued: "I'm expecting a great game in a great environment. A sold-out Selhurst Park and lovely weather is predicted. I think that's why we all love football. The FA Cup, it's Saturday, high noon, so it is everything that we want."
On teenage winger Romain Esse, who joined Palace from Millwall last month, Glasner said: "Every player wants to play the whole time. Of course, I know that maybe it's a special game for Romain, but I never promise any player that he plays. It's all about how the game is going. I have definitely in my mind that he will get some minutes."

Image source, Getty ImagesWe asked for your views on the one thing going on at Crystal Palace that is being overlooked.
Here are some of your comments:
Freddie: Daniel Munoz. From the moment of joining last January, he's added another dimension to our attack, ever present in the opposition box and full of energy in both attack and defence. Finishing has improved over recent weeks as well but for the best part of last year, it rarely got a mention. It wouldn't surprise me if other clubs come "swooping" for one of the most consistently performing Eagles.
Richard: Chris Richards. When Chelsea suddenly recalled Trevoh Chalobah in January, we thought this was going to be a serious problem for a defence that didn't seem to have much strength in depth. But Chris has now become a fixture in a back three that is performing as strongly as ever. He has played an outstanding role in this.
Bill: The massive improvement of Will Hughes. He has been a real anchor in midfield since he has had a run in the side. So much so that he has made himself undroppable. The only fly in his ointment is his disciplinary record, which, with a two-match ban coming up, threatens his continued place in the team.
Richard: I think huge credit has to go to Hughes this season. He's been crucial to the way the team has managed to navigate through the injuries we suffered earlier in the season. He's been a real warrior and leader in the middle of the pitch. While, he lacks pace, he's actually a great footballer, well balanced, good feet, with an eye for a pass and great positional awareness. He is often overlooked when talking about the mercurial talents around him but he pins it all together. Every good team needs a Will Hughes.
Jon: No-one is talking about how good Dean Henderson has been for Palace since he's come in. A lot of fans were sceptical about a large outlay on a goalkeeper who at times had been hit and miss. Especially since we had a decent keeper in Sam Johnstone already. But, since coming into the team, he has done an amazing job and has been a large part in why our defence has been solid with his organisational skills. Not to mention that he makes big saves when he needs to. Getting a few in the face for his troubles.
Olly: Henderson in goal is quietly going about his business. Palace can play out of the back and stretch opponents because of him. Knocking it around at the back, he and the defence draw in opposition players to create space in the middle of the pitch - which allows us to then press quicky - in part because Henderson is so comfortable on the ball. He's become a safe pair of feet as well as a safe pair of hands. But it's not just his short game, his long kicking game is just as decent - often playing the direct route up to Jean-Philippe Mateta. He's doing more than enough to give Thomas Tuchel a selection headache.

Image source, Getty ImagesCrystal Palace chairman Steve Parish says the prospect of an independent regulator in football has "basically paralysed the game".
The Palace chairman and co-owner was speaking at the Financial Times Business of Football Summit, where he spoke about a wide range of topics including Crystal Palace, the Premier League and investment issues in football.
Parish is one of the most vocal in the owners and shareholders meeting and he was asked about what the potential introduction of a regulator could mean for the game.
"We have a problem that we are constantly being told that we are not a business and we're a sport. And that we are part too of the fabric of communities and that we need to prioritise winning over everything else and that's fair and that's why most of us go into it," Parish said.
"And then at the same time, we're in court being treated until the nth degree like a business.
"We have got the spectre of a government regulator as everybody knows, who unfortunately wants to interfere in all the things we don't want them to interfere in and help with none of the things we actually need help with it feels.
"The dynamic of English football has worked outstandingly over the years.
"The various different gravitational pulls of the EFL, the FA, the Premier League have got to the right answer."
However, despite what Parish believes is positive in the current structure, he thinks that the prospect of new rules and a regulator is stopping the game from progressing.
"We are now in a complete paralysis because the government have put this spectre of a regulator and have basically paralysed the game and driven it into the courts," Parish said.
"I don't think that is good but I don't think it is the fault of the Premier League or the Premier League's leadership. I think that there are other factors that have contributed to that and they are doing their best to try and find a way through it.
"And all the time this still - very fortuitously and through a lot of hard work by people at the Premier League - it's one of the few sporting leagues that's growing its media value and growing its appeal globally and we need to take care of that."

Image source, Getty ImagesIt could be an exciting time at Crystal Palace over the next few months.
The Eagles are in good form in the Premier League and are one step away from the FA Cup quarter-finals if they can beat rivals Milwall on Saturday.
But things look to be stepping up off the pitch too.
The club originally submitted plans to redevelop Selhurst Park in 2018 but those plans were delayed due to the pandemic and also the club finishing the work on the academy upgrade.
The club provided an update to supporters in June about the next steps but chairman Steve Parish, who was speaking at the Financial Times Business of Football Summit, says that work on the main stand build should start at the end of the season.
Speaking about a range of topics including investment and the Premier League, Parish said: "Everybody knows we're redeveloping the stadium starting this summer."
The work will increase the capacity of Selhurst Park to 34,000 when completed and is an exciting new chapter for the club.

Jean-Philippe Mateta's form has had plenty of people talking and so has Adam Wharton's shining performance in the thrashing of Aston Villa.
But what is the one thing no-one is talking about at Crystal Palace but really should be?
