Haye keen to take on 'embarrassing' Klitschko

David Haye roared out a warning to world heavyweight champion Wladimir Klitschko after taking just five minutes and four seconds to knock out Enzo Maccarinelli at the O2 Arena in London last night.

Haye will move up to challenge the big boys after adding Maccarinelli's WBO title to the WBC and WBA cruiserweight belts he already owned - and top of his agenda is IBF and WBO king Klitschko.
