Manchester City boss Pep Guardiola admits he studies Chelsea counterpart Thomas Tuchel.

City host Chelsea tomorrow in the early kickoff.

On Tuchel, Guardiola said: "So creative. One of the few managers I learn constantly from, to become a better manager myself. Excellent in all departments.

"I enjoy since in Mainz and Dortmund, always I enjoy watching his teams and the approach.

"He makes world football better. He always wants to be positive in the way they play.

"He [Thomas Tuchel] didn't like the way they played at home so they are going to play a different way.

"Seeing the Liverpool game and Spurs, I saw at Chelsea that they were completely different to what we played in Stamford Bridge.

"Football is every day. The best games were in the last few days.

"Football is constant evolution. You have periods where you play good, the key is to sustain that for as long as possible.

"Tomorrow we face the European champion. An excellent team."
