"We played fantastic. Against a fantastic club, to play the way we did I think is amazing for the boys," Mourinho said after his team had also hit the woodwork three times.
"In the process of building the team, to prepare the team to be favourites, to be one of the favourites next season, I think it is an important step."
Mourinho had said Chelsea would not be "parking the bus" and while they certainly snuffed out City's array of attacking talent, his side also looked dangerous every time they broke and should have added to Branislav Ivanovic's first-half strike.
"They had couple chances but we had better chances to kill the game," Mourinho added. "The players when we didn't have the ball were humble and all ready to defend. When we had the ball they were trying to play and we played really well."
Despite the win secured by fullback Branislav Ivanovic's precise left-foot strike in the first half, Mourinho played down the notion that Chelsea were now favourites to win the title and instead talked about their potential next season.
"It's not our responsibility or our objective to say that (we are favourites). We must complete the puzzle and formation. Some managers it's in their DNA to say we need two, three, four, five years to build,” he said.
"The next pre-season, me and my players will say openly that we are mature, solid from day one and are candidates for the league. This season is about evolution,” he added.
"We can (win the title) if they (City) lose it. Arsenal are working for many, many years for the evolution of their team,” Mourinho said.
It was the first time City had failed to score at home in the league since a 0-0 draw against Birmingham City in November 2010 - a run of 61 games.
