Manchester City boss Pep Guardiola is surprised by their stunning season start.

Guardiola insists he didn't take City's flying start this season for granted with the midweek Champions League draw against Celtic breaking a 10-game winning snap.

"The level of success so far has surprised me," he said. "But this Premier League is so difficult. The fact we won six games in a row does not mean it is easy.

"Before I came here, I was told the Premier League was the toughest in the world, everyone can beat everyone. Now I accept it. I want to give credit to my players."
