That was in a 4-2-3-1 where Jose went with Willian in some big games for his speed in pressing. In a 4-3-3, Cesc is much less dynamic than Rami and Oscar. If we are going to press high, even in a 4-2-3-1, Cesc certainly won't play the 10 role, imo. He just doesn't have the speed and energy of Oscar or Willian.
