The Kiwi WBO heavyweight world boxing champion and his management are considering a massive unification fight against Joshua or Klitschko in London next August.
"Joe could be [at Joshua v Klitschko] to call out the winner for a mega-fight at Wembley in the late summer to unify the belts," Duco Events director David Higgins told The Express.
"That's what we want – to unify the belts and we are willing to lose trying. If the other belt holders shared our views it would fix the heavyweight division.
