But Chelsea are playing the exact same formation!
With much better players and a better manager.
Many would argue that Man City's midfield is the equal if not better than Chelsea. The real problem for City is their defence not being completely solid, and the attacking three being one dimensional.
They've let up, what, 2 goals in the Prem? Don't think their defense is the problem. Their attack wouldn't be one dimensional if they decided to play two strikers, giving someone for Tevez to play off of. Chelsea are using the same formation because they have the players for it, Man City do not. Hence why one team is successful and the other is bland and losing to Sunderland.
