But when he was asked about coming to the Premier League he appeared to take a swipe at old foe Mourinho, who has recently been unveiled as manager of City's arch rivals Manchester United.
He said: "People don't come to the Etihad to see how good the manager is - they come for the players. We have Jose, Klopp, Conte, Pochettino, Koeman. But we are just here to help."

Guardiola added: "The first target is team spirit and play good," he said.
"I know the players, I've played against them many, many times. I know their quality but they have to show me and their fans.
"The past is the past. We are here to try again. My tactic is to develop the players.
Their rivalry goes back to 2011 when Guardiola was Barcelona boss and Mourinho was in charge of Real Madrid.
Talking about Guardiola's Champions League successes, Jose said: "In his first season [Guardiola] lived the scandal of Stamford Bridge, last year he played against a 10-man Inter. Now he is not happy with refs getting it right... If the referee is good everyone will be happy – except Guardiola. He wants them to get it wrong".
The Spaniard responded of the man who used to coach him as a player at the Nou Camp: "In this room, he’s the f****** chief, the f****** man, the person who knows everything about the world and I don’t want to compete with him at all."
It looks like it is going to be an interesting season in Manchester.
