Paris Saint-Germain were expected to cruise through to the quarter-finals of the Champions League against Manchester United on Wednesday night.
The French giants had travelled to Old Trafford a few weeks ago and secured a comfortable 2-0 victory.
Although they were missing Neymar, Man United's injury problems were even worse as they were forced to put five teenagers on the bench.
But, despite all signs pointing towards a PSG victory, United clearly hadn't read the script.
Romelu Lukaku scored a first-half brace before Marcus Rashford's winner from the penalty spot in stoppage time gave them a dramatic victory.

But, many will argue it wasn't deserved.
United attacked in the first leg against PSG, but the emphasis was clearly on defending in the second leg.
They sat back for large periods of the game as they looked to prevent PSG from scoring.
At one point in the first half, they had just 13% possession.
That lead to criticism, including from former Arsenal and Real Madrid player Julio Baptista.
He tweeted in Spanish, but translated to English it reads: "Football has those things!!! Passes for the next round a no-merit Manchester, which was limited to play and defended the whole game, counting on the luck to win the PSG...
"The Manchester being big as it is you can't afford to play like this if you want to win a Champions League."
But, his former teammate at Arsenal, Cesc Fabregas, was quick to jump to Man United's aid.
The Spaniard has been rivals with Man United for much of his career having played for Arsenal and Chelsea, but he felt the need to defend them.
He replied: "Everyone plays with their guns and United had at least eight casualties of very important players.
"They left juvenile boys in the last 20 minutes because they had nothing else. Have you been lucky? Yes. But they deserve respect for fighting and believing until the end."
Fabregas then replied to a fan who criticised United.
"I think you're confused," he tweeted. "I am a defender of good football but you always have to adapt to what you have."
