Derek Chisora and his trainer in punch-up with each other and split ahead of David Haye 'grudge' fight "I won't go into the details as to why he wanted his head gear off and there's a way to tell someone something and it's called respect," Charles told BoxNation, who will show the fight live next month. I regret attacking him because you should never put your hands on someone but I'm a human being with emotions so don't disrespect me. I will not tolerate it. My mother and father don't talk to me like that and certainly not someone I've helped. I don't know if we will rekindle it. He employs me to train him as does his manager (Frank Warren) so it's up to them if I'm fired or not.
