Calzaghe by close decision, like i have said plenty of times Hopkins will make this very rough and dirty fight. And Calzaghe has struggled in rough tough fights before. remember Salem, Bika, Reid, fights. i feel Hopkins will rough up Calzaghe on the inside and make it very tough for Calzaghe and he will offset Calzaghe's rhythm. Hopkins is a master as these kind of fight's and Hopkins is also very tough and dirty fighter so he will give Calzaghe all he can handle, but Calzaghe's work rate will be too much for old Hopkins plus Calzaghe will use angles to good effect to win an ugly UD.
