Oscar de la Hoya has urged David Haye and the Klitschko brothers to resolve their feud in the ring.
Haye's manager Adam Booth has admitted that bitter negotiations to secure the WBA heavyweight king a unification battle with either of the Ukrainian world champions are no nearer a conclusion.
But speaking exclusively to Ringside, six-weight world champion-turned-promoter De la Hoya insists a fight with Vitali or Wladimir can be made - and expects the Londoner to emerge victorious.
"This is a sport, this is what we live for, for these big fights, for these great-name fighters to face each other," he said.
"David Haye, Klitschko - just get in the ring. It will be a great fight, doesn't matter who wins or loses.
"Just as long as it's a great fight, you'll have two winners. It shouldn't be difficult to make; let's get it on.
"David is a great athlete, which I believe is one of his advantages over a Klitschko. He is capable of knocking a Klitschko out.
"It's a very dangerous fight for David, but very winnable."
