Well Kell has worked to bulk up and looks in good shape for a guy who is just turning up for the cheque. There are fighters who enter the title ring with zero confidence like Levinsky against Joe Louis, but our sport is littered with the unfancied overthrowing the betting favourite, so i'm sure Brook believes he can win, whether he will win is another question. "And the new world middleweight champion Kell Brook"
I think Brook believes he can win, he is very conceited, plus he knows that he has his personal referee, judges, boxing commission to help him out, esp. with excessive holding............
I think he believes he can win, but he also knows he's up against it. And he'll try early on up till he realizes the hopelessness of it or gets knocked out.
