Matthew Johnston: LvG must win both the FA Cup and get top four otherwise he's gone. This season's been a disaster. Feel like it still won't be enough.

Danny Mills
Ex-Man City defender at Wembley for BBC Radio 5 live

"Everton have got to bounce back after the Merseyside derby. Martinez shouldn’t have to say a lot in a team talk. 

"He just has to say ‘you embarrassed yourselves go out and put it right'."

Everton's 26th FA Cup semi-final, Manchester United's 28th.

Everton have not won the trophy since 1995 though, and United haven't won it since 2004...

Terrific noise greets the players at Wembley - which is not quite full actually. The pros and cons of playing these games at Wembley have been chewed over plenty of times before. I'd rather see this at Villa Park...

Today is the 400th anniversary of the death of William Shakespeare and our colleagues at BBC Learning have been playing with their ShakespeareMe tool to give us an idea of how the great man might have described the drama of an FA Cup semi-final.

Here's one for both sets of fans...

Have a go with the ShakespeareMe tool here - you enter your emotions and it comes up with a Shakespeare quote to match. 

That might not do BBC One's viewing figures any good.

Yes, if you are wondering what that is all about - 

The new Doctor Who companion will be revealed live on BBC One tonight.

The announcement will be made during half time of the game.

The new companion will star alongside Peter Capaldi's Time Lord in the 10th new season of Doctor Who.

They will replace Jenna Coleman, who played Clara Oswald, who left the show in 2015.

Ex-Everton winger at Wembley with BBC One

"Romelu Lukaku has not been at it since that night at Goodison Park (FA Cup quarter-final). He is not working as hard, not holding the ball up as well, so I’m looking for a big performance tonight."

Alan Shearer
Ex-England captain at Wembley with BBC One

"The best two keepers in league are David De Gea and Hugo Lloris. De Gea has kept United in games this season.

"In the replay against West Ham, it wasn’t until the last few minutes but West Ham tested him and they couldn’t beat him. He’s been fabulous."

There's a lot of pressure on John Stones this evening. He had to come off with illness at Anfield in midweek and was being given the runaround before that. Plus he is playing next to a half-fit Phil Jagielka. And Muhamed Besic is playing at right-back...

Spanish La Liga

Real Madrid went temporarily top of the La Liga table with a comeback victory against Rayo Vallecano a few minutes ago. 

Now Atletico Madrid have the chance to overtake them when they host Malaga at 17:15 BST.

We have live text commentary on that game here.

(Barcelona will go back to the top if they beat Sporting Gijon later)

Alan Shearer
Ex-England captain at Wembley with BBC One

"There is no doubt John Stones has potential but sooner or later the penny has to drop. Stones keeps making the same mistakes at the back for Everton. I'm a big fan of his and he's got huge potential, but he really has to learn."

Manchester United

Manchester United boss Louis van Gaal: "How is an FA Cup semi-final? I don't know yet! It is my first. For us it is exciting, we are very close now but we have to beat Everton. That is our big challenge.

"I am very bored with the discussions about our season. There is no issue. It is always important for us to win a trophy but for Everton also. When you are so close you want to win. Every player and manager wants to win trophies."

And you can also listen to live commentary of the match on BBC Radio 5 live from 17:15 BST. Again, hit live coverage at the top of this page if you want to listen while you read. 

Louis Saha
Ex-Man Utd & Everton striker at Wembley with BBC One

"When you talk about the league it is a marathon, it is not just like a few games playing well, it is about spirit when you play, especially at home. When you go to Goodison you don't feel that now. Maybe the players are in their comfort zone. That is not how it used to be."

Josh Hammond: not doomsday for LVG yet. no silverware or European football at the end of the season then he's gone. A loss today will be a blow

The studio panel can't make their minds up about how high exactly Everton should be finishing in the Premier League but they are unanimous in stating that Roberto Martinez's side are underachieving. 

Could a win today lift the club?

Alan Shearer
Ex-England captain at Wembley with BBC One

"It's been a very disappointing season for Manchester United. Sometimes it just doesn't work for a manager at a club, when the legends of a club and the fans are against you. I don't even think an FA Cup title would be enough for Louis van Gaal. Sometimes your face just doesn't fit."

Kevin Kilbane
Ex-Everton winger at Wembley with BBC One

"For me it's not just about the other night against Liverpool, Everton have been poor for a while now, over the last two seasons. It's the strongest squad they've had in 30 years or so and I think they are seriously under-performing. The FA Cup got Martinez his job, now it could save it."

Everton still fairly empty as we approach kick-off - fans no doubt enjoying the hostelries and attractions around Wembley way...
