Mourinho has only been successful because of the money he spent, and Ferguson as well.
This is the main reason why both of them have such a bad relationship with Wenger, because he was playing great football, winning trophies and spending a fraction of what these two did.
Also, both of them are bad losers, as well as being bad winners, and their lack of class is the opposite of Wenger's more honest approach with the media.
As I said before, it's just a shame Wenger wanted to build our club up to be one of the biggest in Europe, with a new stadium and a bigger fanbase, but lost sight of what was really important, which was winning trophies.
It was almost as if he wants to prove to everyone that his way is the best way, and there is no room for adjustment.
It's this stubbornness and arrogance which means he has to watch all the other top clubs get new managers who are able to adapt and have new ideas while he has remained the same, which clearly can't worked.
