Manchester City boss Sven Goran Eriksson insists there's no need to be concerned about his defence after leaking three goals at Fulham on Saturday night.

"We have to get both right at the same time, we want to be a good Premier League club," he said.

"I am a little bit disappointed. I am not worried, concerned or sleepless.

"I know that we are a new team and a gelling team, and probably we must count on doing some mistakes. But it's much more positive than negative things in the games we've played."

He added: "We will stick to the system because we are doing rather well and I can't see any reasons why we should change that. The type and style of play will be the same.

"We play good football, in almost all the games we play good football. In many games we created a lot of occasions but haven't scored many goals.

"This time we created and scored, but you are never completely happy because we conceded goals a little bit more easily than we did in the past.

"But 3-3, as a show, is better than 0-0."
