Manchester United were on a high going into the Manchester derby on Sunday afternoon.
Jose Mourinho's side had secured three 2-1 wins on the bounce, the most recent of which being their dramatic comeback against Juventus in the Champions League on Wednesday night.
However, United could not keep up their good form as they were defeated by bitter rivals, Man City.
David Silva broke the deadlock after 12 minutes, before Sergio Aguero netted City's second just after the break.
Anthony Martial reduced the deficit by converting from the penalty spot, which set up a nervy finish for the Citizens.
But, Pep Guardiola's side ensured they would be taking home the three points when Ilkay Gundogan struck past David de Gea with four minutes remaining.
In truth, United were not completely humbled on the day, and maybe would have put in a better performance had they been able to call on the services of Paul Pogba.
Pogba's absence meant that Mourinho was forced to restore Marouane Fellaini to the starting line-up.
And after the game, Mourinho made some quite amusing comments about the Belgian midfielder.
The Portuguese international revealed he would have liked to have brought on Fellaini as a sub, and commented how City would have been in 'big, big trouble' if he had got his way.
"He [Fellaini] was not ready to play for 90 minutes," he said, per Miguel Delaney of The Independent.
"I can imagine when it was 2-1 to bring a fresh Fellaini, I think they would be in big, big trouble."
Fellaini has often been criticised by football fans for his ability on the football pitch.
And football fans were rather amused by Mourinho talking up the midfielder.
Even some United fans could not believe what he was saying about Fellaini.
Mourinho admitted he was 'sad but not too disappointed' following the game.
"It was not an easy week for us but I just told the players they’re playing much better than before; we are much stronger, we are much more compact," he said, per the Manchester Evening News. "Now we have to not let the defeat disappoint us.
"Sad, yes, but not too disappointed. In two weeks’ time we play at home against Crystal Palace and, from that game, we have to try to get the points.”News Now - Sport News
