Yet with Juve hosting Valencia later this month, a win for the Italians combined with a United victory against Young Boys at Old Trafford will ensure both clubs make it into the round of 16.
"It's true that the last results gave us good spirit, energy, but the real Manchester United we will see at the end of the season if we can say that we had a good season".
Jose Mourinho's side had looked utterly toothless in attack but after the Portuguese threw on Mata, Marouane Fellaini and Marcus Rashford late in the game they staged the most unlikely of comebacks, recalling their epic 3-2 win from two goals down in Turin in the 1999 semi-finals.
Mourinho has consistently stuck with Romelu Lukaku as his centre-forward, choosing instead to use Sanchez out wide, but with Lukaku injured, Sanchez was given his chance through the middle against Juventus and he impressed.
"I didn't realise it was a fantastic goal until I saw the replay", he said.
Young took the free-kick from the left where there was a scrum of desperate Juventus players trying to keep it out.
Then just after the hour, Bonucci played a wonderful ball over the top for Ronaldo whose side-foot volley whistled past De Gea to open the scoring. If they can show the patience they did against Juventus then it could be a good day for his team.
Sandro's night may have ended in misery but the Brazilian had a moment to remember as he got past Lingard by putting the ball through his legs on the wing during the first half. Martial has scored five goals in the last four games for United.
Pogba didn't excel, but he was well received at his former club on his return to Italy.
It is a big ask for United to stop them, and they will have to play much better than they did against Juve to stand a chance.
And in a post-match interview with Swedish broadcaster Viasat, the United boss also settled another score.
Regardless of how well they are playing, however, it's going to be very tough for them against Manchester City on Sunday. "We played with that spirit and we scored two goals like this". "I wouldn't do that gesture again but I don't think I offended anyone and at the time it seemed like the appropriate response to those who had insulted all my family, apart from my Inter one too".
PSG are third in Group C after their battling 1-1 draw with Napoli in the Stadio San Paolo cauldron, and while they are only one point behind leaders Liverpool, Tuchel's side have only managed to beat Red Star Belgrade in four matches.
