"I think we are not going to be relegated", the United boss said brusquely, before offering an upbeat analysis of a game in which Martial's penalty was their only shot on target and their goal difference went into negative figures. We paid for the mistakes.
DF Ashley Young, 6 - Struggled to deal with the left-sided combination of David Silva and Raheem Sterling, leaving space in behind twice before the City pair took advantage for the first goal.
David Silva opened the scoring for scintillating City and Sergio Aguero added a second three minutes into the second half.
"I don't go for stats, I go for what I felt and I watch in the game and the game was there until minute 80-something".
"He can carry the ball and he can play the pass".
Teammate Gundogan joked that the pair were talking about Aguero's new haircut.
Something did go right for United after Lingard was replaced by Romelu Lukaku.
Mourinho had picked a team to defend and play for a point.
But Ilkay Gundogan put the result beyond doubt four minutes from time with a third goal that crowned a sublime 44-pass move.
The global break is next, and the team's will return to the field on November 24. Not as the team that appears to use elaborate financial mechanisms to try to avoid failing sporting financial regulations, as the Abu Dhabi ownership has been accused of doing after internal correspondence leaked over the last week.
City raced out of the blocks and were nearly ahead inside two minutes.
"Despite that, we were stable, we score one goal, the first 15 minutes was so good and after that we didn't press so well".
"I'm not going to give that as an excuse", said Mourinho, a three-time Premier League victor with Chelsea.
"Everybody has to agree", Mourinho said.
They often say that you can prove anything with stats, on Sunday they proved that United just weren't very good.
"It's another thing to beat Shakhtar Donetsk at home and enjoy the game and be relaxed. For different reasons we missed Paul but that doesn't mean with Paul we win the game so it's not an excuse".
"I thought United were in deep trouble when I found out he wasn't playing, a midfield of (Nemanja) Matic, Fellaini and (Ander) Herrera I was thinking how are they going to get the ball through midfield and transfer it".
