Deontay Wilder made Anthony Joshua eat his words on Saturday night as the American knocked out Dominic Breazeale in the first round.
It took the Bronze Bomber just two minutes and 17 seconds to seal his 41st career victory after AJ said he wanted the fight to go nine rounds.
His prediction couldn't have been further off the mark.
"Styles make fights, I think Wilder will fare well against Breazeale," said Joshua. "I think Wilder is too quick, he's a very, very fast heavyweight.
"But Breazeale is tough, he took me seven rounds. I hope Wilder does it in nine, so I can be like, 'Hey I done it earlier.'"
Wilder's knockout was emphatic as he caught Breazeale on the chin with a powerful right hook and floored the 33-year-old.
His punch sent the Barclays Center wild - even the commentators.
Mauro Ranallo was the commentator for the fight and his reaction to Wilder's knock-out blow was something special.
"Oooh, Wilder hit Breazeale so hard they are feeling it in Brazil. Mamma mia, what a KO!" shouted Ranallo before adding: "He just put Breazeale's body in airplane mode!"

Ranallo was stunned and so was every other boxing fan watching the fight as Wilder made easy work of Breazeale, who was expected to put up a good fight.
Wilder will now be eyeing up a unification bout with Joshua, who currently holds the IBF, WBA (Super) and WBO belts.
