Former heavyweight world champion and Hall of Famer George Foreman is confidently backing Tyson Fury to defeat Anthony Joshua.

Fury, who holds the WBC title, could potentially face WBA, WBO, IBF, IBO champion Joshua in 2021.

Fury solidified himself as the top guy in the weight class in February, when he dropped and stopped Deontay Wilder in seven rounds to capture the WBC title at the MGM Grand in Las Vegas.

Foreman has a lot of respect for Fury's boxing ability.

"That boy Tyson Fury, you’re gonna have to bring everything you’ve got to beat him.  And I’m going to be honest with you, I just can’t see Joshua beating him. But I sure would buy some tickets to see what would happen, I’m that curious about it," Foreman said to IFL TV. 

Foreman also gave his stake on Wilder suffering his first career defeat.

After the fight, Wilder blamed his loss on a variety of reasons - including a heavy ring-walk outfit, which the boxer claimed had weakened his legs.

There is a trilogy fight in play, after Wilder exercised an immediate rematch clause.

Foreman believes Wilder can come back from his first loss - but he has to come to grips with the reasons for his defeat.

"When I lost to Muhammad Ali in Africa all those years back, the ropes were loose, someone put something in my water, it was too early in the morning – oh, the excuses went on," Foreman said.

"You’ve got to have excuses when you lose, especially when you’re undefeated. You can’t just say, 'I lost.' You can’t say that! And that’s gravity, that’s putting yourself solidly down to make an excellent comeback. He can come back and he can win again, easily. All fighters can."
