Rich: That's gotta be the fastest ever.

It is, beating Louis Saha's opener for Everton against Chelsea after 25 seconds in 2009.

Thirteen seconds! Unlucky for Manchester United. Absolute joy for Manchester City's fans.

It's an unbelievable strike from Gundogan and De gea is just rooted. All sorts of dip on that ball! What a start to the game.

What did I say just before kick-off about Manchester City and their fast starts?

Admittedly, I did not expect one quite as fast as that.

Manchester United did not get themselves organised.

For them, that was a complete disaster.

That goal at 13 seconds is, unsurprisingly, the fastest ever scored in an FA Cup final.

It's a team that we are so used to seeing play out from the back but here they go back to Stefan Ortega and then long to Erling Haaland.

It's just a moment of brilliance from the Manchester City captain. The technique is something else. Ilkay Gudogan has stepped up with important goals at the end of the season and he's done it again.

Manchester City get the all-Manchester FA Cup final under way.

From Sir Alex Ferguson's demeanour, you can tell he is up for this game.

After bringing the trophy out with Mike Summerbee, he saluted the Manchester United fans with a familiar clenched fist, then he shook Erik ten Hag's hand and gave him a slap on the back as the teams came out.

It is 2007 since he last managed in an FA Cup final, when United lost to Chelsea. It is 2004 since he won one.

I bet he wishes he could turn the clock back.

Mark: As a local unattached onlooker I think United should resist playing out from the back. City will swarm all over them and add to that de Gea's poor passing, disaster looms. Old fashioned long ball with flick ons for United's speedy forwards

The final words of the national anthem prompt a burst of the pitch side fireworks, the two sets of players then shake each others' hands before taking up their positions.

Here. We. Go.

An incredible sea of colour at Wembley. Flames shoot into the air as both teams emerge from the tunnel. The noise from the stands is off the scale.

The FA Cup final really is an incredible occasion, the best in English football no doubt.

Pep Guardiola and Erik ten Hag share a quick hug before leading their respective teams out. What an atmosphere as they emerge.

Christian Eriksen on Manchester City's recent form speaking to BBC 5 Live before the game:

"I think its the aim and the dream of every club and you want to win the Premier League as many times as possible."

On Manchester United's improvements this season:

"I think definitely with the manager and structure we now have a big shot of winning the Premier League. To win the FA Cup will be very special and I am really excited for the game.

"The history is a big part of it, with the generation before they won everything and now that's the target of the club and it's what we are trying to do."

Andrew: An awful lot of things all need to fall in favour of Manchester United today if they are to lift the FA Cup and end City’s treble bid. United have a real lack of impact quality from the bench, especially when compared with Pep’s options.

Before Manchester United won the last derby at Old Trafford in January, Manchester City had come out on top in the previous three.

In every one of those meetings, they scored inside the first 10 minutes.

It goes without saying Pep Guardiola's side will look to make an equally fast start today - and United will be desperate to stop them.

James: FA Cup finals should move back to 3pm kick-offs for good.

Prince William is chatting with the mascots in the tunnel, Sir Alex Ferguson and Mike Summerbee are stood at the entrance holding the FA Cup trophy, Wembley is a sea of blue and red. There's a real sense of excitement and expectation in the air.
