David Haye told Ringside that he is prepared to earn himself a bout with Vitali Klitschko.
The Londoner, who lost his WBA heavyweight title to Vitali's brother, Wladimir, in July 2011, recently announced that he will return to boxing in Manchester on June 29.
Haye is eager to face 41-year old WBC champion Klitschko but thinks he may have to wait a while following his dominant victory over fellow Brit Dereck Chisora last summer.
However, the Bermondsey-born puncher says that will not faze him and insists that he will fight his way into contention for another opportunity at world title gold.
"Wladimir says he doesn't want to fight me and that's fair because he beat me before, but Vitali said publicly that after I beat Chisora he would fight me and knock me out," said Haye, who entered the I'm a Celebrity, Get Me Out of Here! jungle before Christmas.
"However, he probably thought Chisora would give me a harder night's work and didn't anticipate me knocking him out in five rounds.
"I think my performance was too good for Vitali, who has looked laboured in his last few fights and not at his all-time best, and may want to go another route
"But in the interim I'm going to stay busy, knock people out, work up the rankings and become a mandatory challenger because I want to regain the heavyweight championship of the world."
Sky Sports commentator and former world lightweight champion Jim Watt says he always thought Haye would lace up his gloves again - and reckons the 32-year-old's comeback to boxing will be more than just fleeting.
"David is a world-class fighter, which is something you cannot say about an awful lot of the heavyweights out there, and I thought he would come back because he is a terrific athlete," said Watt.
"I did think he might have waited until the Klitschkos moved aside, but he has probably realised now that the brothers are fighting so far within themselves that they could do it forever.
"He now really wants them and I like the fact he is going to do it the right way and earn a crack, as last time he talked his way into a world title - though well done to him for doing that.
"Once he is number one in the rankings and has bargaining power, he can make a lot of money - and he will be in boxing as long as there are big purses for him."
Ex-European super-bantamweight titlist Spencer Oliver added: "I think the defeat to Wladimir was so convincing that David needed to come back, but he has to fight a top-ranked fighter, someone like Alexander Povetkin, Tony Thompson or Chris Arreola.
"David, who brings so much power and excitement, got things wrong against Wladimir but if he gets it right against Vitali, who is a little bit slower, then he has got a great chance of beating him."
