"Rooney has developed into a real leader hasn't he? He's excelled at striker but we know he can do a job in midfield, and that appears to be where he thinks his future is, playing a deeper more withdrawn role." 

Dan Walker and the boys are wandering through the bowels of Wembley on Football Focus.

"Martial is a sensation. He's like Thierry Henry. This is what he does so well - he teases the defenders on the wing then stops, gets going and beats people."

"Anthony Martial actually has a really good shot conversion rate. Manchester United haven't created too many chances this season so for Martial to score as many goals as he has, in his first season, he's done really well."

"At the start of the season United manager Louis van Gaal said he wanted Champions League football. In that sense the season has been a failure. But if he can win this trophy then you can take from the campaign.

"The two big decisions are whether Marouane Fellaini will come back into the midfield. I think Van Gaal will go with Juan Mata for his experience instead of Jesse Lingard."

"Louis van Gaal is odds on to lose his job regardless of today's result. There's constant rumour and reports about Mourinho taking the job, that puts pressure on. In the league Man Utd haven't been good enough, but to win the FA Cup, that could be the catalyst for future success."

"When you've lost twice it stays with you more than the victories. Palace manager Alan Pardew knows what an FA Cup final feels like.

"Everyone is fully fit for the London side. Palace's biggest threat will come from out wide from Wilfried Zaha and Yannick Bolasie.

"If you have the front three of Palace you know on their day they can be match-winners."

"Crystal Palace have only had seven wins since the turn of the year - and five of those in the FA Cup. It's not really good enough with the talent they have in the side, but they've probably concentrated on the cup run."

The best action Villa Park has seen all season...

"Palace's biggest threat will come from out wide. Defensively they've been quite solid - that's something Alan Pardew has really worked on. So if they can contain United, they'll need Wilfried Zaha and Yannick Bolasie to really perform."

"Like Wayne Rooney's been saying, I think today's really important not just for the immediate future and Louis van Gaal but for this new generation of Manchester United players coming through. It's about gathering momentum for years to come."

"Its obviously a massive day out. I'm not so sure he will get sacked regardless of whether United win or lose. If United win then I think van Gaal will stay."

So, this one might need some explaining... John Guidetti has played seven times for Sweden and was on the books at Man City for a bit.

"The FA Cup final was the day of the season growing up, it was everything. Watching the build-up from this time of the day right until kick-off. The memories you savour."

Phil Neville
Former Manchester Untied defender at Wembley with Football Focus

"The FA Cup final is such a massive occasion. As soon as as these two teams won their semi-finals the players will have been dreaming about today, about this game, There'll be tension, nerves, despair and excitement. I really can't wait."
