Oleksandr Usyk has called out Tyson Fury immediately after retaining his heavyweight titles with a split decision victory over Anthony Joshua in Jeddah on Saturday.

The Ukrainian's victory over Joshua meant he retained the WBA, WBO and IBF belts, while he also claimed the Ring Magazine belt.

Usyk is now eyeing off the WBC belt, vacated by Fury who had declared he was retired after beating Killian Whyte in April. Fury had recently indicated he would end his retirement to potentially fight Derek Chisora before flip-flopping on that decision earlier this month.

However, speculation has mounted that Fury would come out of retirement to face the winner of Saturday's bout.

That will only be fueled by the video posted by the 'Gypsy King' on Twitter reacting to Usyk's victory, claiming he would "annihilate" both fighters, while the 35-year-old Ukrainian was already eyeing off a bout with him.

"I'm sure Tyson Fury isn't retired yet," Usyk said on the ring immediately after the bout.

"I'm sure he wants to fight me. I want to fight him. If I'm not fighting Tyson Fury, I'm not fighting at all."

Fury said on Twitter: "It was one of the worst heavyweight title fights I have ever seen. I would annihilate both of them on the same night.

"Get your f*****g chequebook out because the Gypsy King is here to stay forever."

Fury's co-promoter Frank Warren had indicated earlier this month that the 34-year-old was getting "itchy feet" in retirement.

"He's got itchy feet at the moment, he wants to fight," he told TalkSPORT.

"I think what's going to happen is, see what happens on [August] 20th and the outcome of that and that'll determine what he intends to do in the future.

"My opinion, this is not from him, it's from me. I think he will [return] because he's a fighting man and he misses it. That's what he does, he wants to fight."
