Mourinho was overjoyed with the first half performance, in particular.
"(Chelsea were) afraid to say 'we want to win, we can win'," Mourinho said.
"We played very, very well. If we can play like this against Man City, why can't we play like this in every match in the Premier League? That is the self-esteem we need.
"We played fantastic against a fantastic team. And that's not easy. We were better than them. And that's not easy."
