One of the biggest criticisms of Louis Van Gaal has been his arrogant attitude. Its something many people find charming in Chelsea manager Jose Mourinho, but Van Gaal takes his self-confidence to a new level. The Dutchman has always been very confident of his ability all through his career, and one of his former players Luca Toni - from his Bayern Munich tenure - gave an insight to how inflated Van Gaals ego really was. The coach wanted to make clear to us that he can drop any player, it was all the same to him because, as he said, he had the balls. He demonstrated this literally by dropping his trousers. I have never experienced anything like it, it was totally crazy. Luckily, I didnt see a lot, because I wasnt in the front row, said the former Bayern striker. Van Gaal is a manager considered very unorthodox by many of his former players. Hes a man who is regarded as highly arrogant, which comes as a surprise considering how many humbling experiences hes had with a host of former clubs. The below quotes from Van Gaal, as reported by Sky Sports, highlight exactly what he thinks of himself. "I know I'm a very good coach. I am who I am: confident, arrogant, dominant, honest, hard-working and innovative. When I think I've made an error, it can cause me a sleepless night. But that only happens rarely." "I am the way I am and I've not got an easy-going manner. But I'm not going to change my personality just because some people want me to. Running is for animals. You need a brain and a ball for football."
