Rooney, Gerrard, Yaya, Xavi and Pirlo

These are great players especially those midfielders but could we have been overrating their value to their respective teams?Liverpool seems to have been unshackled after Gerrard left, Juventus were unstoppable last year after Pirlo left and City are playing really well without Yaya. The only people who seem to have left huge gaps are Scholes and Lampard
