I’d go for Oleksandr Usyk. Achieved everything at cruiserweight against a lot of great fighters and he’s not a big heavyweight so for him to go up to that weight and win convincingly against Joshua is an incredible feat.

Always been a huge fan of Román González. You realise how good he is when you sit and watch him and his last fight was unbelievable. He’s got to be right up there. Naoya Inoue’s up there. I think some of the little fighters don’t get the credit.

For me it’s Tyson Fury who’s the best in the world right now.

I would say Oleksandr Usyk. To win Olympic gold, become undisputed champion and then move up to heavyweight to beat one of the best in the division is legendary behaviour. He may not beat Tyson Fury, but what he has done should not be scoffed at.
