Wladimir Klitschko has revealed the “five-step plan” he believes will re-establish him as the world’s leading heavyweight when he meets Anthony Joshua in his “signature” fight.

The 40-year-old hopes to regain two of the titles he lost to Tyson Fury when he challenges IBF champion Joshua at Wembley on April 29, when the vacant WBA title will also be fought for.

He has often been dismissed as in decline since that shock defeat by Fury in 2015, but is adamant the fact he has not fought since then will be to his advantage on an occasion expected to attract a post-war British record boxing crowd of 90,000 fans.

“In the first step, my target is to become a three-time world champion,” said Klitschko.

“I’ve been holding myself back for a year and a half, which is the first time in my 26-year career.

“The second step is the consequences. When I win this fight, I will help (Joshua) come back.

“In the third step, I need to have some way to get in shape. So I will have sparring partners: my direct competitors that want to knock me out in sparring sessions.

“We’re (me and Joshua) probably going to look at the same guys, because we’re the same size. So those sparring partners will definitely help me get something back.

“The fourth step, standing in the middle of this stadium, holding those belts in my hands to all the fans. I’m imagining it.

“Fifth, the final step, which is very important to me, is I am obsessed with my goal to become champion.”

Klitschko caused intrigue by acknowledging the fight’s significance despite others against David Haye, Alexander Povetkin and others in the United States being similarly big.
