"It feels perfect! The game was not perfect but it was very good," he said after the 4-1 win at The Etihad Stadium.
"City couldn't start like they want but that is important for us. We played with big passion and that's the most important thing for us.
"The good news is that we can do better. At half-time I told the boys they were surprised to be winning 3-0, and we must do better in that situation.
"We have quality, we could have more goals but 4-1 is perfect. The boys can believe now that they are stronger than many people think."
