The Blues put in a brilliant display away from home to stop their free-scoring opponents and move themselves level with them on points, although they remain third on goal difference.
And even though the victory means they’re just two points behind table toppers Arsenal, the Portuguese boss has insisted they’re not in the title race this season.
He told Sky Sports:
“It’s not our responsibility or objective to do that [win the league]. Our objective is to build the team.
“I want to start the next pre-season in the summer and say this season we are going to win the league. This season I can’t.
“We are not top guns. We are a team who is evolving.”
However, despite his reluctance to lay claim to the league title this season, Mourinho thinks the result against City gives him plenty to be positive about.
“We played fantastic. Against a fantastic team, to play the way we did is amazing,” he added.
“The process of building the team and preparing the team to be favourites as we want to be the favourites next season, this is a very important step.
“The best team in the Premier League – we have beaten them twice in the Premier League.
“It’s very important because it’s not good for the evolution of the team if we are playing 10 or 15 points behind or in the Europa League. We need big things and these kind of matches and the pressure we had today.
“The feeling of playing the way they played is a fantastic feeling for them.”
