Watch Dillian Whyte knock down Anthony Joshua about 2.45 of video then he goes on to win an Unamious decision. http://www.youtube.com/watch?v=BDSH8cXtFRQ Good scrap for an amateur bout.
Joshua looked horrible in that fight, but it means f-all really. He's very much learning on the job and there's no shame in that.
Whyte is 9-0 as a professional. He's currently on a ban for doping. He's still young, about 25 I think. Joshua has yet to face an opponent as credible as Whyte in the pro ranks.
