United fell 11 points behind Pep Guardiola’s side with a 2-1 loss at Old Trafford on Sunday.
The scoreline was even kinder than the game suggested, as the Red Devils spent most of the match pinned in their own half.
Mourinho’s reputation was tarnished furthermore by the fracas in the tunnel after the final whistle, where he was accused of trying to storm the City dressing room.
It was reported that the Portuguese boss unhappy with the loud music and ‘over-celebrating’.
And Sky Sports pundit Alan Smith thinks that City will have too much for United this season in the title race.
But he has not ruled out Mourinho strengthening his team to bounce back next year.
“I think it takes a team as good as Manchester City to prevent him winning the league,” Smith told Sky Sports’ The Debate show.
“I think he can still win the league again, definitely.
“He knows what it takes, if he has got the players he can organise them into a title winning team.
“At the moment that is not quite good enough but he can be in the future.”
Fellow pundit Gordon Strachan also had his say on the matter.
“I think he has got intelligence in abundance,” the former Scotland boss added.
“He has got plenty going for him. He knows so much about the game.
“Again, sometime you hit a plateau as a coach and sometimes you need do do something else.”
