Tyson Fury's father John Fury has hit out at Anthony Joshua's reaction to the loss against Oleksandr Usyk, saying he showed he wasn't a 'warrior'.
The London 2012 Olympic champion suffered only his second career defeat against Usyk last month, conceding his numerous heavyweight titles in the process.
That has put a proposed unification bout against Fury in doubt, with Joshua now set for a rematch with the Ukrainian after activated a clause in his contract.
For Joshua to open the doors for a fight against Fury, he'll need to win back the titles he lost - but John Fury has questioned his approach.
Joshua was widely criticised for his reaction to the defeat, immediately returning to the dressing room after the conclusion of the bout, and John Fury believes his whole attitude outlined why he wouldn't be able to defeat his son.
"You've only got to look at Joshua's body language after the fight, his behaviour on the stool. His behaviour, warriors don't behave like that,â€ he told the True Geordie podcast.
"If you look at Tyson and you look at Deontay Wilder - Deontay Wilder dipped his head much to say I've give me all I can't do anymore, he was just all out.
"He wasn't making any emotions like he was discomforted, he wasn't trying to do anything but soak it all in. Deontay Wilder fought his heart out, he had nothing left at all. I think he was teetering on being conscious when he was sat on his stool.
â€œAJ didn't do anything wrong, you can only do what you can do in boxing. He just hasn't got the desire or the will - not a quarter of it of these other two men, Wilder or my son.
â€œHonestly he's been a good champion, but does he ever beat these other two men. Definitely not, because he's not a one punch knockout artist like Wilder either."
