Pep Guardiola insists he will not allow complacency to creep in at the Etihad Stadium, despite Manchester City's excellent start to the campaign.
Saturday's 4-0 victory over Bournemouth made it five straight wins for City in the Premier League, and eight in all competitions under the Spaniard.
City have scored 25 goals across those eight games but manager Guardiola says his squad will not become overconfident.
"That is not going to happen when I am there," he said.
"And don't say it is too easy. I heard from years ago the Premier League is the toughest league and I am going to accept that.
"We have a lot of work to do and we are just in September. We have played absolutely nothing.
"Always for the next game, we have to try to do it better than the game before."
Guardiola is remaining grounded, acknowledging there will be tough moments ahead, and added: "I am so happy but I have to tell you I am going to lose games.
"We won these five games in the Premier League and the people have very nice words but we know what happens in our world.
"I have seen what happens when the trainer didn't win, they have been so critical and they didn't deserve that. It is better to stay back and don't read too much.
"I know we are going to lose games and it is important when that happens to be stable."
