Kessler looks like the guy Calzaghe should fight. I watched the Mundine and Lucas fights and was very impressed. He's huge at super middle and punches hard with the right. His defense looked sound against Mundine and he was able to time him from the outside much better than previous opponents. He fights at a pretty measured pace so someone who has quick feet, a good chin and the ability to work hard for 12 rounds could outwork him. I don't see anyone other than Calzaghe who meets this description
