Game, set and match? Jake Forster-Caskey reckons so as he converts from the spot after Perez Colunga was sent tumbling in the box by Jordan Turnbull.
All over and Stadium:mk explodes into a cacophony of noise. It is a famous victory for the MK Dons and a night of unwanted records for Manchester United and manager Louis van Gaal.
They have conceded four goals in a League Cup match against lower league opposition for the first time, and it's the first time since 1995 they have been knocked out in the second round.
Celtic lose their Champions League play-off 2-1 on aggregate to NK Maribor and drop into the Europa League. Marcos Tavares punishing poor defending to force home a shot on 75 minutes and secure a 1-0 away win tonight. Head here for reaction.
An extra-winner? Possibly, as Brighton's Perez Colunga scores from close-range following good work from Adam Chicksen.
Ahsan Ahmed: , externalEmbarassing regardless of which XI is on the pitch. Shocking.
Freddie Hunt:, external The 3-5-2 system clearly doesn't work in English football. Every goal the ball was given away.
Allan McDevitt:, external Humiliating of course but what is most concerning is the form of players like Januzaj tonight.
Four minutes of stoppage time announced. Four minutes for Manchester United fans to endure, four minutes for MK Dons fans to savour.
Another 30 here...
Manchester United fans are belting out some defiant songs but stony silence on the bench as Louis van Gaal and Ryan Giggs watch on, no doubt stunned by what has unfolded.
James Wilson is valiantly trying to save some face for United as his downward header is pushed behind.

"That fourth goal probably summed it up in a nutshell, Afobe just wanted it more. It's gallows humour from the United fans, they've been brilliant. But what they've watched beggars belief and borders on the disgraceful. I don't think we'll see to many of these players in a United shirt again if this is anything to go by."
Crewe substitute Marcus Haber ghosts in at the far post to head home a Bradden Inman cross and level the scores at the death.
All square at full-time and this one is going to extra time too.
Jack Cork opened his Saints' account earlier in the night and Graziano Pelle has done the same to close out the game.
Fantastic stuff from MK Dons and fantastic stuff from Benik Afobe! The Manchester United defence are at sixes and sevens as they try to deal with the burly striker but he powers his way through to the area and confidently slots home. Surely this is one of the all-time great upsets?
Adnan Januzaj smashes an effort against the outside of the post as he tries to reduce the deficit, but the home fans are unperturbed. They remain in full voice as their side close in on a famous victory. Just over five minutes left.
