Wednesday night's 3-1 victory over Paris Saint-Germain in the Champions League last 16 was a historic moment for Manchester United.
It meant they progressed into the quarter-finals despite losing the first leg 2-0 and no one giving them a chance of recovering.
Interim manager Ole Gunnar Solskjaer is now certain to be given the permanent job after producing nothing short of a miracle.
Sir Alex Ferguson was in attendance at the Parc des Princes and there's no question that Solskjaer has his former mentor's blessing.
United's players did Solskjaer proud on the pitch as they defended valiantly against one of the world's most dangerous players, Kylian Mbappe, and took their chances.
The Red Devils were fortunate to be awarded a 90th-minute penalty when the ball struck Presnel Kimpembe's arm and the referee consulted VAR, but they were fantastic nonetheless.
At the final whistle there were scenes of jubilation as United players and staff wildly celebrated with the travelling fans in the corner of the stadium.
And the celebrations continued behind the scenes, too, judging by Chris Smalling's comments in a recent interview with Sky Sports.
Smalling claims there was a "really good vibe" in the dressing room and apparently even Sir Alex and Eric Cantona joined in.
Fergie went round to every player shaking their hand and saying "congratulations", while Cantona told them how "proud" he was of the way they played to win the game.
"It was [lively in the changing room] - moments like that you've got to savour and take in," said Smalling. "Obviously seeing Eric in the changing room and Sir Alex.
"It was great to see everyone come together, all the board, the owners, and then seeing Eric come through with everyone singing his name, it was just a really good vibe.
"Sir Alex came around and shook everyone's hand, saying congratulations. Eric said a little bit, that he was proud to watch the team play and win like that. Generally happy vibes. [It was] unbelievable."
Reports claim Solskjaer allowed his players to all have a drink on the flight back to Manchester, but Smalling insists that wasn't the case.
"To be honest, we weren't," the Englishman added. "[Solskjaer] didn't say either way. Andreas [Pereira] and Fred were in the corner playing their music. It was just nice and chilled."
