I actually think the whole thing has gone to Hatton's head these past few years, since the Tszyu fight Hatton has had an army of fans telling him how wonderful he is and he really has believed them all!!
He loses to Mayweather, but the excuse is Mayweather is the best fighter in the world, no shame there he thinks. He then fights Paquiao and is not competitive at all for 2 rounds and gets Knocked out cold!
I can't see how this is his trainer's fault? If his camp wasn't a happy one leading up to the fight i do not see how this made any difference to the demolition job Pacquiao did on him. It sounds more like Hatton was going to do it his way no matter who was in his corner and that's just ego!
