Hatton was never gonna win that, too many people were betting with their hearts instead of their heads - he was out of his class, reach disadvantage, weight (and height?) disadvantage and when he got through he just didn't have the power to make it count.
That said, Mayweather is a typical egotistical ####!!, the kind everyone hates. Hatton can at least come home with his head held high... but sorry mate, that's what happens when you try to be a Bertie Big Bollocks like that.
