VITALI KLITSCHKO claims he would finish off David Haye quicker than his brother Wladimir.But WBC champion Vitali doubts the Briton will want to fight him - or his sibling - in a world heavyweight title unification clash this year.
Vitali defends his title against Albert Sosnowski in Germany on Saturday and is desperate to then face WBA champ Haye.
Vitali, 38, said: "I promise David Haye that the fight with me would be much shorter than with my brother.
"I will knock him out in two, three or a maximum of four rounds.
"Haye tries to use every excuse why he doesn't want to fight us - but nobody believes him."
