Cech believes Chelsea will be one of the sides up there fighting for silverware come May.
Asked if the title race was already restricted to just the top three sides, he said: "It looks like it, because they (Manchester City and United) have been focussed on getting points.
"We lost some points, they did at the start of the season. So it looks like we'll be the three teams that chase the title.
"But let's not forget the others, because any game is difficult and you can drop points against any teams."
