The Etihad Stadium was a scene of emotion all day, with players and staff in tears after the final whistle.
"I'm so happy, and the way it was makes it a little bit better but let's not try to repeat that again," said Silva. "There was a bit of disbelief and we still had to believe in the turnaround.
"When you beat a team as good as Liverpool, it feels better. We have won it the last few years against top, top teams.
"But once again we are the best team in England and next year we will try to come back and give a bit more to the fans."
