DAVID HAYE claimed Oleksandr Usyk must improve his defence if he is to be successful at heavyweight.
Haye was ringside to watch Usyk knockout Tony Bellew in round eight of their undisputed cruiserweight world title fight.
PA:Press Association6 Usyk is the current undisputed cruiserweight world champion, but he admitted a move up to heavyweight is the plan
Usyk had previously admitted he was eyeing a future fight with unified world heavyweight champion Anthony Joshua.
However, Haye cited Usyk was hit too often against his former rival Bellew, as ‘Bomber’ found himself ahead on two of the judges scorecards before he was KO’d.
The former two-weight world champion told BoxingScene.com that Usyk cannot afford to be on the receiving end of that many shots if it is Joshua or WBC king Deontay Wilder throwing the punches.
Haye said: “The shots he was taking tonight against Bellew, you don’t wanna be taking those shots from a Joshua or a Deontay Wilder.

“His defense wasn’t as slick as I thought it was going into this fight. He was getting counter-punched, he was getting hit at range.”
Usyk, the current WBC, WBA, IBF and WBO cruiserweight king, already penned a deal with promoter Eddie Hearn and Matchroom Boxing – leaving a fight with Joshua or Dillian Whyte a huge possibility.
Usyk also competed as an amateur at heavyweight, before moving down to campaign at cruiserweight as a pro.
But Haye claimed Usyk may struggle to move up in weight due to the size of modern day heavyweights such as Joshua, Wilder and Tyson Fury.
