And here's Nedum's team.

Jaap Stam, who is alongside the pair for Football Focus this afternoon, is handily in both teams to save for any awkward moments.

Thoughts on both teams? Who would make your combined XI?

On Football Focus, Dion Dublin and Nedum Onuoha were tasked with coming up with their combined XI from Manchester United's Treble winning team from 1999 and Manchester City's current side, who could also win a Treble this season.

This is Dion's team:

We asked you to pick your combined Manchester City and Manchester United teams and this is what you came up with.

Disagree with your fellow football fans? Then you can still pick your team here.

Arthur M: As a Man Utd fan whose on his way to the game, I have absolutely no hope in my team today. With Haaland and KDB most likely in the line-up, if we start Maguire and Lindelof again I may as well leave.

Tony: I’m a United fan but simply hope City don’t thrash us - if United score early we have a chance, if City score early it could be a cricket score.

Trust me, I've seen Neil fiddle about with a camera phone. They were definitely holding that pose for a while.

This is Manchester City fan Mazem and his wife Arouba posing outside Wembley before it got busy. They have travelled all the way from Lebanon in the Middle East in the hope of securing tickets for a once-in-a-lifetime experience.

"My dream is to watch City play at Wembley," Mazem tells me.

They deserve tickets just for holding this pose for a couple of minutes while I fiddled about with my camera phone.

The last time an FA Cup clash between Manchester City and Manchester United was shown live on the BBC was way back in 1996.

It was fifth-round tie and featured goals, scuffles, and Mick Hucknall's half-time analysis.

Peak 90s stuff - have a watch below.

Peter: This feels like the biggest FA Cup final in many years. It’s City v United, so that elevates it. And it’s being played after the season, given its own weekend with nothing to detract from it. This is how it should be, not relegated to a side show played on the same day as PL.

Manchester City striker Erling Haaland says he "will do everything" to help the club to a historic Treble.

City have won this season's Premier League and can add to that if they beat Manchester United in the FA Cup final on Saturday and Inter Milan in the Champions League final on 10 June.

United won each of those trophies in 1999 and are the only English club to have done such a Treble.

"It would be unreal to make this history," Haaland told BBC sports editor Dan Roan.

"This is why they bought me of course, to get this, we don't have to hide that.

"It would mean everything. I will do everything I possibly can to try to make it happen. It's my biggest dream and hopefully dreams do come true."

A teenager who had brain cancer has been invited to take a half-time penalty kick at the FA Cup final.

Edward, a 14-year-old from Cirencester, was diagnosed with the cancer in September 2020.

On the day of his final operation in August 2021, Edward launched a campaign to raise money for Brain Tumour Research., external

Edward's "100 Strikes Against Cancer" challenge , externalinvolves taking 100 penalty kicks at 100 different locations - whether it's in a field with makeshift goalposts or in a stadium at a cup final - with the hopes of raising £100,000 for Brain Tumour Research.

The idea came to him whilst he was going through a "horrendous" treatment programme which consisted of multiple operations, high-dose radiotherapy and months of chemotherapy.

His parents said: "Each kick is a major achievement for a boy who came out of surgery unable to walk or talk."

The Mayor of Greater Manchester, Andy Burnham, spoke to Sportshour on BBC World Service earlier today about just how big a game this is for the city.

“This is football history," he said. "The first all Manchester FA Cup final. It’s a massive day for the city region which I lead. I will be there as a very impartial mayor as I support a different club so I can sit on the fence but I am proud of the city of Manchester today.

"This may be controversial but I think Manchester is the biggest football city in the world. Madrid is big, Milan is big but I don’t think either have two football clubs with the same stature as Manchester any more. So this is the biggest football city in the world with its first all Manchester FA Cup final what a day!"

Twin sisters Talia (left) and Alexis are on opposing sides at Wembley.

"I'll be in tears if City lose," Talia, 12, from Bury, says.

Meanwhile, Alexis says she is going to change her top before kick-off because the family have tickets in the City end.

Awkward.

Past players from both clubs are cheering on their respective former sides from afar.

Here's ex-Manchester United midfielder Bastian Schweinsteiger, who tweeted this picture along with the caption: "Come on Manchester United!"

Under three hours before kick-off and the streets surrounding Wembley are a sea of blue and red.

There's a carnival atmosphere with fans mixing together in the sunshine. Lots of chat about how many Erling Haaland and Marcus Rashford will score.

Many of the fans I have spoken to today set off at the crack of dawn to be here and they're determined to have a good time.

I’ve just been treated to a run-through of the pyrotechnics that will greet the players as they enter the arena. Will we be seeing more fireworks once the match kicks off?

Jaap Stam
Former Manchester United defender on BBC One

If you focus fully on Haaland then others players will step up and take advantage. United need to be aggressive to avoid letting City settle into a rhythm.

United must use their pace up front and try to get Rashford in behind as often as possible. They need to be calm and confident in possession.

Nedum Onuoha
Former Manchester City defender on Final Score

I am a nervous wreck. This is a one off game. In City's quest to win a Treble it has to start with a double. Some people are thinking it is a foregone conclusion but it is anything but that. Manchester United won the League Cup, they finished third and finished on a win.

Dion Dublin
Former Manchester United striker on Final Score

Maybe two or three years ago the FA Cup lost its spark a bit but now I feel it is stronger than ever.

It has always been there for me and all footballers want to win this. It is so special.

Manchester City's team coach is parked up outside the team hotel a short distance from Wembley Stadium waiting to take Pep Guardiola's side to the final.

There's already a few Manchester United fans in position outside ready to 'cheer' City's Treble-chasing players when they emerge.
