Wladimir Klitschko has announced he will take up the option of a rematch with Tyson Fury.
Klitschko surrendered his heavyweight world titles to Fury in Dusseldorf on Saturday night in one of the biggest upsets in boxing history.
The 39-year-old, who had previously been unbeaten in nine years, was outpointed by his British opponent after 12 disappointing rounds.
There had been suggestions the Ukrainian could hang up his gloves following Fury’s deserved victory, but he has now decided he wants to win back his WBA, IBF and WBO belts.
A statement released from Klitschko on Wednesday read: “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, Klitschko’s manager, added: “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.”
