Koeman had too much arrogance. He thought he was bigger than the club. Seem more like a dictator.... Banning Niasse without giving him a chance to prove is a No No for me.Ironically, Niasse saved his ass few weeks back i guess..Maybe there was a silent revolt by the players over many weeks, if not, no way, the players turn bad over night and play without drive,determination or fire.... Yes,Koeman left, now let's look ahead...
