Juan Mata's free-kick was equally effective as United looked to have nicked a point. 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.
"I was very pleased to score my first Champions League goal for Juventus, but we're in good shape. It was a game where we could have lost 2-0, drew the game 1-1 or won the game 2-1", he added.
"Manchester United did nothing to win the game".
The goal looked to be enough to win the game and secure top spot and qualification for the knockout stages with two games to spare for Massimiliano Allegri's team.
Paul Pogba's return did not quite go so well against his former club and he again struggled to show his best form. It was clear at times that his confidence is still low: after all, he entered Wednesday's game having scored just four times in 27 appearances, and his appearances this season have been sporadic at best. They nearly let United back into it at Old Trafford after switching off and this time they were punished for missing gilt-edge chances by a cynical away side. It's a very open competition this year with several teams capable of going all the way, especially with the holders, Real Madrid, lacking Ronaldo.
Lukaku's injury means he is a doubt for Sunday's trip to Manchester City, so Sanchez might get another outing at the Etihad.
A confident Mata knew he had to take the set-piece. City have scored 12 goals in their last two matches and are in unbelievable form, with Riyad Mahrez showing why he was right to leave Leicester and join a bigger club.
But there was more drama to come as Ashley Young whipped the ball on and it was bundled home off the face of Alex Sandro. Juventus beat Cagliari 3-1 over the weekend.
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. "And especially there is always a lot of negative comments about us but hopefully they might say something positive for once, because I think we deserve it, the team deserve it, the manager deserves it for getting this fantastic result".
