And, whether you believe Weah or not, they certainly did not see anything wrong with the way he was treated. There really is no right or wrong here. Just a difference of mentality. Too many English clubs are steeped in the old mentality where the manager micromanages everything and is God, father figure and nanny rolled into one. His authority must never be questioned, his word is final and he can talk to the players any way he wants.
Reality is quite different.
George Weah is not just any old player. He is used to a certain way of doing things. Perhaps to Royle the fact that the club cleaned his boots is a big concession. Royle probably thought that reading Weah the riot act in front of his teammates was a good way to motivate him. To Weah, it was merely insulting.
