Andy Ruiz Jr has slammed Tyson Fury by claiming that he can only stay relevant by targeting him for his weight.
The superstar Brit, 31, has previously taunted Anthony Joshua for getting "knocked out by a fat guy."
But the 29-year-old Ruiz has admitted that he is a fan of Fury and won't stoop down to his level.
"Tyson Fury, he wants to be relevant," the unified champ told TMZ.
"He wants to be in the scene. I like the guy, too. I'm a big fan of him.
"I like how he is. I like his energy."
Fury will return to action next Saturday when he takes on little-known Otto Wallin at the T-Mobile Arena in Las Vegas.
But the 'Gypsy King' recently took a shot at Ruiz by branding him as an "average boxer."
He told ESPN: "Hand speed doesn't just cut it. There's a lot of heavyweights who have hand speed.
"I can beat him with one hand tied behind me back. And even if they want me to stay against the ropes, I'd still beat him out there.
"All these guys are bums compared to me. I'm going to prove that time and time again.
"I'm going to go down in history as the greatest heavyweight of all time."
Joshua, who will have his rematch with Ruiz on 7th December, recently admitted that Fury trolls him by randomly calling him up and telling him that he'll 'knock him out.'
But 'AJ,' 29, has fired back at his fellow Brit's call for him to retire should he lose against the 'Destroyer' in the rematch in Saudi Arabia.
Fury has continued to taunt Joshua after he told ESPN that the superstar Brit is a "big bum" and "eats right hands for fun."
Will 'AJ' beat Ruiz in the rematch?
Let us know in the comments.
