However, Cech has defended his manager, insisting there will always be difficult selection decisions at Chelsea due to the squad's strength in depth.
Cech told Sky Sports News: "If Joe Cole played and Ballack played, but (Frank) Lampard or (Salomon) Kalou or someone else was not in they (the critics) would say the same thing.
"We have a large squad, we have 27 top players, and the manager has a difficult decision to choose 11 to play.
"He chooses what he thinks is the strongest XI. If we had won the game these questions would not have been asked."
