The Portuguese hailed his side's 1-0 victory over Manchester City on Monday night, but he believes it is only an "important step" and that Chelsea is not a favorite for the title
The Portuguese watched his side negate City's attack - which had found the net in their last 61 top-flight home games - to claim a 1-0 win and inflict a first domestic home defeat of the season on Manuel Pellegrini's men.
Branislav Ivanovic's goal in the 32nd minute proved enough to secure all three points, but Chelsea - which beat City 2-1 at Stamford Bridge in the reverse fixture - refused to sit back on the lead and hit the woodwork on three separate occasions.
And while Mourinho was delighted to see his team produce such an effective performance, hailing the three points as a crucial milestone in Chelsea's development, he refused to label his side as a title favorite.
"I think we played fantastic, to play the way we did is amazing," he told Sky Sports. "In this process of building the team to be one of the favorites for next season this is a very important step.
"The best team in the Premier League - we beat them twice, today we were fantastic.
"We had the better chances to kill the game, the players played with fantastic spirit. When they had the ball we were very humble and ready to work defensively, when we had the ball we played and played really well.
"We are there, but not favorites. For the team it's very important, the feeling is fantastic feeling for them. Today we won because we were the best team, not better than them but today they were fabulous.
"It is not our objective to win (the title this season), our objective is to build the team and complete the formation of the players.
"I want to start next preseason and say this season we are going to compete and be one of the favorites."
