My gut says it should be Haye - He did even more trash talking and lost clearly, whereas I feel Degale won by a round. But for some reason I going to go with Degale. I think he is just more of a comedy fool in general.
PLUS, he made it a lot worse in the fool-stakes when he lept up when they announced 'and still undefeated...' thinking that it was him and then quickly pulled his arms back down when he realised he was thick, then actually nearly doing it again when they said 'and now British AND Commenwealth champion'. Oh the shame.
