Manchester City skipper Kolo Toure admits their defensive frailties are letting them down.

City drew their fifth successive game on Saturday after the 3-3 result with Burnley.

"We know we dropped two points - we have to improve our defending," he told City's website. "We need time and work and there's still a long way to go. The manager has highlighted a few things. We have top-class players, and we have to take responsibility at the back.

"As defenders, we need to work like brothers. We feel vulnerable at the moment, which isn't good. We have to be stronger. When the opposition score three goals like that, it's difficult to take. It's killing me.

"We're very, very disappointed because we came back so well in the second half to score three goals. But at the end we left some space at the back again, and that's the second home game where we have not defended well.

"As captain I'll take the responsibility, but we'll all work on it when we are all back in training. It is something we have to address if we are to be a top four team."
