Wladimir Klitschko has revealed he will exercise his right to a rematch with Tyson Fury.
The Morecambe giant outboxed the Ukrainian great on Saturday night in Dusseldorf to hand him a first defeat in 11 years and take his spot as the undisputed heavyweight king.
Many thought the 39-year-old could retire.
But instead he will bid to win his titles back in 2016 as per a clause in the big-fight contract.
Klitschko said: “I was really frustrated directly after the fight.
“But after some short nights I now know that I want to show that I am much better than my performance on Saturday.
“I couldn’t show my full potential at any time.
“This is what I want to change in the rematch – and I will. Failure is not an option.”
Bernd Bönte, CEO Klitschko Management Group (KMG): “There will be a huge worldwide interest in this fight, which already can be billed as the fight of the year 2016.
“We received so many questions of fans and journalists after last Saturday.
“The new champion and his challenger will answer all of them inside the ring,” he added.
The date and venue for the contest are to be thrashed out by K2 Promotions and Hennessy Sports with Fury’s team understood to want to bring the fight to England, possibly at Wembley Stadium.
