Former undisputed heavyweight champion Lennox Lewis believes Tyson Fury - because of his awkward style and physical abilities- is more difficult to beat than WBC champion Deontay Wilder and IBF, IBO, WBA, WBO champion Anthony Joshua.
Fury is back in the ring this coming Saturday night in Belfast, when he faces world title challenger Francescko Pianeta.
Should Fury win, he would return in the fall - potentially in a blockbuster Showtime Pay-Per-View fight against Wilder.
And the winner of that fight would move ahead to a possibly unification with Joshua in April 2019, at Wembley in London.
Joshua, who was in talks to fight Wilder in the fall, is facing mandatory challenger Alexander Povetkin of Russia on September 22 in Wembley.
Lewis was very disappointed when Joshua failed to reach an agreement to face Wilder - but he's very happy that Fury is close to a deal to challenge the WBC champion.
Fury, who back in June snapped a layoff that began after his huge win over Wladimir Klitschko in 2015, is looking to face Wilder first and then Joshua in a five belt unification.
"They are all very good in their different ways. Which is why I want to see them all fight each other the way we did in the last golden age for heavyweights. It would be fascinating to see which way it shakes out," Lewis told Daily Mail.
"Anthony has a terrific right hand which makes him dangerous. Deontay has an even bigger right which completely concusses anyone if he connects and he is also faster on his feet.
"Tyson is perhaps the most difficult to beat. He is remarkably mobile and athletic for a man 6ft 9in tall and has that very long reach to go with it. His evasive style makes him very awkward to get to. I would have boxed each one differently."
