You know nothing about Man Utd.
Valencia, De Gea, Smalling, Jones are still strong players under Jose. All are Sir Alex players. Even Moyes recruits of Fellaini and Mata play almost every game. LVG signings of Martial, Blind and Darmian are constant players. Rashford and Lindgard have also continued their rise under Jose as they did for LVG.
Sir Alex played a big role in convincing Jose to join Man Utd.
Your criticism of Jose fits perfectly with gossip columns and opposing fans skewed view. For example in his first interview after Jose signed as Man Utd manager, he was in MUTV and he said he has finally joined a club that's bigger than him and all players. Man Utd. Rooney also said he asked to return home to Everton since he knew he couldn't start ahead of the new stars as he wished. Jose turned him down twice before emotionally agreeing to let him go. Man Utd board waved his last year contract fee compensation that Everton was meant to pay to sign him. This was a kind gesture to say thanks for the glorious 12 years service and thanks too that Everton gave us the chance to have him back then.
Kweli wewe ni jirani.
