It is very rare you hear of any player past or present even remotely criticizing Jose for any reason whatsoever.
The players appear to love him and this is reflected in how they play for him. He is a top, top class football manager.
Pellegrini is nowhere near him as a football manager. Nowhere.
That is why he is a mediocre football manager at best.
Before you start the abuse ask yourself this question:
With our squad and with Jose as the manager in the last 2 years would we have won more and achieved more?
