Haye happy to play underdog
The 30-year-old WBA champion is notoriously cocky and outspoken but has historically backed up his boasts by undertaking tough challenges and coming out on top.
His two biggest wins, against Jean Marc Mormeck for the cruiserweight world title in 2007 and Nikolay Valuev for the WBA heavyweight crown in 2009, took place on foreign soil against heavy betting favourites. On Saturday in Hamburg he ventures into hostile territory again to face 35-year-old Klitschko, the long-standing IBF and WBO champion who holds significant height and weight advantages. But Haye (25-1, 23KOs) would not have it any other way.
