We await reaction from either camp. Cambridge are off celebrating while Louis van Gaal and co slope off to the tunnel. Van Gaal named such a strong side, he will not be happy.

BBC Sport at the Abbey Stadium"If you're wondering why Cambridge United's players are not swapping shirts with Manchester United's players it's because they have to pay to replace them if they do swap!"

Dion Dublin said before the game that his dream result was for Cambridge to get a draw which took them back to Old Trafford. He's got his wish.

Alan Shearer
BBC Sport"It's a dream come true for Cambridge. Yes Manchester United had chances but so they should do. Cambridge are 12th in League Two and there was nothing between them for large periods."

Former Cambridge United striker Steve Claridge
BBC Sport"Absolutely deserved. There was nothing fluky about this. Cambridge stuck to their task incredibly. They didn't give Manchester United anything at all, and I have seen United play an awful lot worse than this. These sort of games give you the impetus to go on and have a real go in the league. The result here changes the whole season."

Cambridge winger Ryan Donaldson: "It was hard! really hard. We got penned in but they have world class players and a draw is a dream result for us.
"They had two great chances in the second half and we will take a draw any day. It's going to be surreal at Old Trafford but we have been to Wembley twice last year - not bad is it?"

Flares off in the stands, players on each other's shoulders - picture book stuff. The fans are loving this, and quite right too...

It's all over! Cambridge have held on to earn a replay at Old Trafford. The place erupts, you'd think they had won the FA Cup!
A fine scene. This is what the FA Cup can still do. A great achievement from these 18 men and the coaching staff.

What a save. Heroic stuff from Chris Dunn and that could be that...

BBC Sport"Chris Dunn has absolutely clattered Robin van Persie, he smashes him and then makes a wonderful save from the resultant volley from Angel Di Maria. Great play from the goalkeeper."

Brilliant from Chris Dunn! He comes off his line to punch away from in front of Robin van Persie, Angel Di Maria hammers in the rebound on the volley and Dunn is down low to save! His back four then scramble it clear.
A £1m save?

He's been brilliant all night but just when it could really matter, Ryan Donaldson serves up a terrible free-kick, chipped down the middle and right at David De Gea. An easy hold.

BBC Sport"Cambridge United have come back into it a bit now, and maybe it's Manchester United who will have a nervy end of the game. You wouldn't begrudge them this, Cambridge. If any team has ever earned a replay in the FA Cup, they have tonight."

At the hour mark or so a Manchester United winner looked a certainty. now, I'm not so sure. Cambridge have been excellent, they really have.
That is a chance for the visitors though, Radamel Falcao heading over under heavy pressure.

Abbey Stadium is bouncing. This is Cambridge's best spell in 40 or more minutes as another long ball into the box is dealt with well.
Luke Shaw comes on to replace Daley Blind at left-back.
