Tyson Fury wants to fight Anthony Joshua in his first fight back after more than two years away from the ring.
The former world heavyweight champion has not fought since dethroning Wladimir Klitschko in November 2015.
Fury has been back in the gym in recent months, however, ahead of a proposed comeback in 2018. And the 29-year-old wants to jump straight in at the deep end and face the WBA and IBF king, Joshua.
“As a sporting challenge I lay down the challenge for @anthonyfjoshua to fight me in my first fight back in over 2.5 years,” Fury wrote on Twitter.
“I’m the best heavyweight on the planet come prove I’m not? The ball is in your court don’t let your fans down CHAMP.”
He continued: “I’m that good I don’t need any warm ups I can come off the couch and beat up on @anthonyfjoshua don’t run your big a*** in the bush, let’s fight this summer!”
The self-styled Gypsy King has blown up in weight since losing his world titles amid self-confessed problems with drugs and depression.
But he has been training alongside former two-weight world champion Ricky Hatton as he bids to return to his throne.
Joshua, meanwhile, stopped Klitschko in April 2017 and is set to sign to fight New Zealand’s WBO champion Joseph Parker in the spring.
