Manchester City winger Kevin de Bruyne says they'll learn a lot about themselves after today's derby at Manchester United.

De Bruyne is relishing the occasion and hopes to land an early blow on a potential title rival, but accepts that could count for little in the long run.

The Belgium playmaker said: "I don't think winning this game gives the team a psychological edge. It can turn so quickly in football.

"You try to win a lot of games in a row to gain an advantage but it can turn quickly, like we had last year. If you lose four or five games in a row it can be done and impossible to come back.

"It means a little bit more because it's a big game - you want to prove yourself in the first really big test of the year to show everybody that we're ready - but if we lose then it is only three points.

"I want to be there at the end, not at the beginning. If we can do it now and maintain it then that's even nicer."
