Haye will knock Klitschko out - McGuigan

Former world featherweight boxing champion Barry McGuigan says he is "convinced" David Haye will knock out Wladimir Klitschko in Saturday's heavyweight unification bout.

McGuigan adds that 90% of the boxing world believe that IBF and WBO heavyweight champion Klitschko will win, but he is backing Haye's punching power to prevail.
