The competition for places will mean that anyone can be dropped which means the players have to perform week in week out. This I believe will give City that extra edge that will win them the title. Putting my cards on the table I know but I just think they will. It's up to United and Chelsea to prove me wrong and I reckon United will. Whenever City win well, United just seem to win better. Mancini obviously believes challenging his players will make them perform better, will interesting to see how that turns out.
