Walking this earth like a (very drugged up) god back into the ring, because he's probably almost through his huge Joshua payday already.
He'll probably end up bankrupt having smoked all the millions he got for the Joshua fight and make an ill advised come back. If he's smart he'll do what Briggs has done and try to talk his way into a big fight and then retire rather than try and earn a shot, he could easily get beaten should he fight anyone half decent.
I am 100% sure he will do some sort of "investment" (usually giving money to friends and family who then start a businesses such as restaurants, real estate companies etc) and it blows up. Then he will blame "bad advisors" and people who mismanaged his finances. Woudlnt' surprise me the least if a guy like Povetkin offered him a fight in 2017 or 2018 in Moscow after his PED fallout. Martin's record looks OK on paper and maybe he's marketable to gullibe Russian fans.
