Andy Lee has sent out a warning to Deontay Wilder ahead of his trilogy installment in Las Vegas against Tyson Fury.
The Irishman - who will be in Fury's corner alongside SugarHill Steward - is confident of history repeat itself when the pair collide on October 9.
The rematch in February 2020 saw the "Gypsy King" destroy Wilder inside seven rounds, dropping him three times on his way to winning the WBC heavyweight title.
In doing so, Fury became just the second fighter after Riddick Bowe in the division to win all four world titles in his career - the other three being the WBA, IBF, and WBO.
Lee, a former world champion-turned-trainer, believes Fury is going to 'smash' his American rival.
"Tyson's trained really well in Morcombe, he's flying out to Vegas on September 18 and do the last four weeks in Vegas. We're going to kick Wilder's ass, smash him," Lee exclusively told Planet Sport.
"He's feeling good it was probably a blessing in disguise that he had a rest, he needed it," Lee said after being asked if Fury had recovered from Covid-19.
"He hasn't had any rest at all since the second Wilder fight he's been training every day and he needed a rest. He's fresh and training well."
Joshua vs Fury can happen next
The fight the world wants to see is Anthony Joshua against Fury for the undisputed championship.
Both men need to come through their respective opponents next for it to come into fruition.
Before Fury takes on Wilder, AJ will be back in action against WBO mandatory challenger Oleksandr Usyk.
The Ukrainian contender is the former undisputed champion at 200lbs and retired Tony Bellew in 2019.
Since moving up to heavyweight, he has defeated Chazz Witherspoon and Derek Chisora - the latter being his most recent bout in October 2020.
Usyk - a live underdog with Planet Sport Bet - is bidding to become just a third fighter to unify the cruiserweight division and win a world title at heavyweight - the other two being Evander Holyfield and David Haye.
Lee believes Joshua's size may prove decisive in the encounter and expects Joshua-Fury to be made if both come through.
"They always say a good big man beats a good small man but Usyk has a bit of the X-Factor, he's got the amateur pedigree but I think Joshua is still improving and too big.
"Very high I think (of Joshua-Fury happening). Before the arbitration, it was a done deal so if Tyson can do the business and Joshua does the business then it's on."
