Shannon Briggs has thrown down the challenge to fellow former world heavyweight champion David Haye.
Briggs (59-6-1-KO52) is now 44 but has won eight on the trot - including six first-round stoppages - since losing a unanimous decision to Vitali Klitschko in 2010.
Haye (27-2-KO25) recently returned from a three-and-a-half year break from the sport but showed no ill effects in blasting Mark de Mori aside at The O2 in January and quickly announced his next bout will be on May 21.
And Briggs took to social media to make himself available, claiming: "Breaking news. I'm going to invade England!
"David Haye! Let's go champ! Let's go champ! Let's give the people what they want to see.
"I'm headed to the #UnitedKingdom to raise hell. If anyone in England's interested in helping me find an apartment or flat I'd appreciate it. Anyone interested in being in my camp when I get there email me... I'm looking for sparring as well."
The last time anyone was able to halt Briggs was way back in 1998, when then-WBC world heavyweight champion Lennox Lewis stopped him in five rounds.
