Speaking on talkSPORT’s ‘The Verdict’ podcast with George Groves, he said:
“I think the only thing Usyk will do is retire, he will either have the rematch or retire.
“He’s got nothing to prove. He’s beaten AJ twice, he’s now beaten Tyson Fury.
“He is the generational great for me. Usyk is the main, he is the leader of the pack.
“When you look back at this generation of heavyweights you’re going to look back and say ‘Oleksandr Usyk is the main man, he’s dominated’
“In my opinion, he should retire, he’s done everything he needs to do, he’s made enough money, he’s mastered the game, he’s completed boxing.
“There is nothing left to do. undisputed cruiserweight, undisputed heavyweight, 37 years old, getting towards 40.
“When I retired I was nearly 37. Usyk is at that age where I know how you feel in training camp and how you feel in round seven and eight.
“He’s completed boxing, hang up the gloves, and turn it in. That is my advice to him.
“I don’t think he’s got anything left to prove, the rematch proves nothing.
“Anthony Joshua, Tyson Fury and the rest of the heavyweights can fight for the number two position.”
Tyson Fury has activated the rematch clause according to Frank Warren so Oleksandr Usyk and Fury could collide again later this year.
