Yep I think that Tszyu beats him not only does Tszyu apply pressure like Castano but he is more skilled and hits much harder than Castano. I think that Tszyu would break him down and stop him late. Charlo would have a punchers chance so can't count him out but I favor Tszyu.
Charlo reacted very strongly to a simple question about the potential of fighting Tyszu in the future. Tim is a bit flat footed at times but I think he has the power to worry Charlo and judging from his response, I suspect Charlo might already be a bit worried!
