Essien got injured very early on last season, We don't need that happening again. You cannot compare Carlo's rotation with Ranieri's because resting 1-3 players is different from resting 6-8, Resting players keeps our team fresh, United do it, Liverpool do it badly and Arsenal don't do it, It shows when they finish 4th every season. We will get unhappy players if they don't have game time, Rotation gives quality players game time all the time, Whats the use of a 90% Michael Essien when we have an 100% Mikel? I'd like all our players to be at there best, and rotation lets us do this. Maybe you will see the importance of Rotation and Stregth in depth when the Champions League group stages come in.
