Anthony Joshua believes what he needs to beat Ukrainian heavyweight Wladimir Klitschko is to be unleashed in the ring.
Joshua who holds the IBF heavyweight title will battle Klitschko for the vacant WBA and IBO titles at the Wembley Stadium come April 29.
There has been respect between both boxers in the build up to their much awaited bout, but the undefeated Brit won’t show any towards Klitschko in the ring.
“Come the night I have to be a killer,” said Joshua, at a promotional event in Germany on Thursday. “If you are not a killer in this game, you get eaten alive.”
“I’m like a tamed animal – until I’m let off the leash in the ring,” he added.
Fury afforded Klitschko little respect in the build-up to their clash and the Ukrainian has been quick to praise Joshua’s altogether more courteous manner this time round.
“It is refreshingly different from the British boxers I fought before,” said Klitschko, who was also forced to engage in a war of words with David Haye back in 2011.
“Anthony is proof that it is not about nationality, but personality. The respect we are showing each other for this fight is good for boxing. It is what boxing needs.
“This fight does not need the pretend bullying, It is a match-maker’s dream. Look at 90,000 fans coming to Wembley. I am glad to be going to London now. The British are great people who love their sport.”
Joshua will be in possession of three of the five major titles in the heavyweight division if he beats Klitschko, with Wilder and Parker holding the WBC and WBO belts respectively.
However, the British fighter insists he has no right to view himself as the No 1 heavyweight in the world until he unifies the division.
“There will still be work to be done before I can think of making that claim,” Joshua said.
“I might see myself as the universal heavyweight champion if I unify all the titles. That’s not easy to do with so many mandatory defences for the different belts but that’s my aim.
“I look at what Wladimir has done in the last 14 years. He can’t go on another 14 years. But I can. That is my pathway to reigning as the heavyweight champion for a long time.
“Wladimir is a great champion but my legacy is beginning. I admire his experience but basically I believe this is a young man’s sport.”
