Wladimir Klitschko has hinted he could return to the boxing ring after asking his social media followers for their thoughts on him fighting Anthony Joshua, Deontay Wilder or Tyson Fury.
Former heavyweight world champion Klitschko has not fought since Joshua stopped him in the 11th round of an epic April 2017 bout at Wembley that saw both men sent to the canvas.
That left the Ukrainian's record at 64-5 and in August 2017 Klitschko announced he was ending his 21-year career.

However, on Saturday he alluded to a potential U-turn as he asked fans for their views on him fighting WBA, IBF and WBO champion Joshua, WBC belt holder Wilder or Fury, who stunned Klitschko with a points win in 2015.
"Let me entertain you with this and you can like it or not: Fury vs Klitschko 2," he wrote before posting two follow-up tweets changing Fury's name for those of Joshua and Wilder.
Klitschko only fought once after his loss to Fury and it was that rematch that was garnering the most 'likes' on Twitter.

The heavyweight division has rebounded since Klitschko's retirement, with Joshua, Fury, Wilder and Andy Ruiz putting on some classic fights.
Just last weekend, Joshua avenged the first loss of his professional career when he earned a lop-sided unanimous decision win over Ruiz in Saudi Arabia.
Ruiz scored the biggest upset of the year when he knocked Joshua out in the Englishman's US debut at Madison Square Garden in June.
Fury and Wilder fought to a controversial draw late last year and will reportedly run it back in February.
Wilder is coming off a stunning seventh round knockout win over Luis Ortiz in Las Vegas in November.
Having probably lost every round until that point, Wilder landed a powerful short right hand to the top of Ortiz's head.
Ortiz wobbled back to his feet, but the bout was stopped.
