The players are out on the pitch and they line up around the centre circle to observe a two minutes silence to remember Prince Philip following the Duke of Edinburgh's funeral service earlier today.

This should be a cracking game. It could be a huge six weeks for both clubs. The demand for success is massive.

The talent of Mason Mount is incredible, the vision he has. He's got a huge future ahead of him. He gets into the position, the confidence he has in himself, he's difficult to pick up. He can pull teams apart.

Chelsea are very close to achieving what would have been a goal of theirs at the start of the season - a place in the top four and one or two bits of silverware. When you have those things to aim for at the end of a season, you’re in a good place.

I don’t think they’ll be scared going into this game - they’ll have a plan. Are they going to find those moments for Timo Werner and Hakim Ziyech to put the ball in the back of the net?

Jord Gurr: I don't cheer Chelsea often but can't be having a quadruple.

Rob Millward: If I was Tuchel I'd be telling Mount to get at Mendy. Mount and Ziyech against him could really be a deciding factor in this.

John Arundell: Looking forward to the match. I think if Chelsea are going to win they need to strike first.

Chelsea boss Thomas Tuchel, speaking to BBC Sport about his first trip to Wembley: "Quite impressive obviously. Dressing room is huge, manager's office is huge! Shame the stadium is empty, would have been great to see it full but we want to make the most of it.

"If you play Manchester City or Bayern Munich it is the biggest test you can have right now. Like I have said we want to close the gap. We have come here to show we can close it."

Thomas Tuchel has failed to beat Pep Guardiola in five attempts as a manager - two games with Mainz and three at Borussia Dortmund, all when Guardiola was in charge at Bayern Munich.

Zack Steffen is a steady keeper. He doesn’t make too many mistakes. He doesn’t have the footwork of Ederson. He’s a safe pair of hands. He’s not let Manchester City down before.

This game could be a banana skin for City because they’re playing a very, very good Chelsea side.

The team that’s gone out there - not one of them will be thinking about a treble or quadruple or anything. Pep will be looking at this one as his most important focus.

Zack Steffen has won all 10 of his games with Manchester City.

He's conceded just five goals in these games (five clean sheets), shipping more goals against teams from a lower league (three in four games) than top-flight sides (two in six games)

Manchester City boss Pep Guardiola, speaking to BBC Sport: "Semi-final of the FA Cup - the most traditional competition around the world. Pleasure to be here.

"Champions League we struggled to break that bridge from the quarter-finals but we did it. No time with this schedule to enjoy the good moments or be depressed in the bad ones.

"It will be an incredible tough game. They are one of the best sides in Europe right now. An incredible manager. The quality of Chelsea was always there.

"A tough, tough, tough game."

On Zack Steffen starting in goal: "Since I started my managerial career always in cup competitions I play the second keeper. It is fair to do this."

This will be a very tough game for Chelsea with the way City are playing, their confidence. On the flip side Chelsea are playing with a lot of confidence. Thomas Tuchel has transformed this team.

Chelsea are good on the counter-attack and City have to be wary of that. City have a lot of possession as we know, but they do leave a lot of space in behind. It happens time and time again.

If Chelsea play with pace up front, they could cause City problems.

There's no fans at Wembley today but the stadium still looks impressive in the bright sunshine with the stands decked out in giant flags and banners.

Chelsea are up against one of the best managers in the world. He finds solutions and ways to break down the opposition in detail.

Pep Guardiola will go with his game plan, the way he wants his team to play in and out of possession. I don’t think he’ll be too concerned about the way Chelsea’s approach.

Lee Dixon
Former Arsenal and England defender on BBC Radio 5 Live

You look at the City bench - every single one of them would make a difference. They’ve got an unbelievable squad and they’ll push it right to the end today.

I’m really excited about this game today. It’ll be a great game of football because Chelsea will be bang up for this.
