Ivanovic believes that, after extending the 100 percent start at home with a fifth win, the current squad are as good as the one which lifted the Premier League under Carlo Ancelotti.
The Serbia defender said: "We have a different team now to the one that won the league in 2010, but maybe we have the same quality and performances (as that team) to win the league this season.
"We have a strong enough squad, if we stay at this level to be competitive.
"To be champions and stay at the top all season, it is very important to get maximum points from every game.
"Sometimes it may be only a point but we have to get something from every game, especially when we are at home. We're doing that well this season.
"The champions aren't decided now, but it was so important for us to beat Manchester City because these kind of games give you confidence and extra points when you are fighting for them.
"I hope it's going to help our confidence and in the next games as well."
