Nobody was expecting that scoreline. There you have United winning, playing really well towards the end, but all the focus is still on what the manager did after the game.
But United are no slouches in Turin.
He said: "It made me feel at home as well, even if I play for Manchester United, they were very welcoming and I really appreciate that".
Outside of one draw, Juventus have won every game they have played this season. Anthony Martial continued his hot streak, scoring in United's 2-1 win over Bournemouth.
Juan Mata helped his side equalise through a flawless free-kick from right outside the penalty box. They bought that player (Ronaldo), they want to win everything, they can win everything and we are a team where numerous players didn't play big matches like this in the Champions League.
Minutes later, Marouane Fellaini flicked on a free kick and the ball ricocheted around near the far post before going in off Juventus defender Alex Sandro. Juventus were doubly stunned when United scored again three minutes later. Juventus' defense will again be hard for United to play against.
Cristiano Ronaldo's magnificent volley had Juve on course for victory but it was the visitors who would land a stunning blow in a Champions League clash to cherish.
United's players sprinted towards their manager in delight. They face Young Boys then Valencia.
A fortnight after being outclassed by Juventus at Old Trafford, victory at the Allianz Stadium represented a lot more than just a boost to United's prospects of reaching the Champions League knockout stages.
There has been more confidence and attacking intent about the team in recent weeks, looking at their best when their backs are to the wall and when they are underdogs with the vultures circling.
"Today we did a big step, but it's not over yet."
"We carried on, we pushed and we know that we can be unsafe on free-kicks because they defend very well (in open play)".
"I didn't realise it was a fantastic goal until I saw the replay", he said.
Paul Pogba's return did not quite go so well against his former club and he again struggled to show his best form.
Juve needed something special to break the United resistance and they got it when Bonucci's hopeful long ball from his own half dropped into the path of Ronaldo, who lashed it home on 65 minutes. United's man in form and their most unsafe forward again.
A night of triumph for Manchester United in the Champions League produces glorious echoes of the Red Devils' European heyday.
