Manchester City midfielder Kevin de Bruyne says they must not be complacent facing Bayern Munich.
City go to Germany for the second-leg of their Champions League quarterfinal with a 3-0 advantage.
But De Bruyne insists: "There is still a long way to go. There aren't 50 minutes left and you need to cover up a bit. It's 95 minutes and a lot can happen.
"You have heard about crazy results in many games, so we will have to bring our 'A-game'.
"We don't think we are speculating about keeping the lead. We just play the game we know we want to play.
"We are moving on again, and we know it will be difficult. When you meet Bayern, they have a lot of quality, but we would rather be ahead by three than the opposite."
