Tyson Fury believes Andy Ruiz will knockout Anthony Joshua for the second time when they meet for a rematch in Saudi Arabia this winter.
The December 7 bout, branded 'Clash on the Dunes', will see Joshua bid to win back the IBF, WBA and WBO titles that he lost back in June when Ruiz Jr sent him to the canvas four times en route to a stunning upset at Madison Square Garden.
In an exclusive interview with ESPN, Fury said: "I'm a big believer in when one door closes, another one opens and it was all about Joshua at that time when he was fighting Ruiz.
"When he fought Ruiz, no-one gave him [Ruiz] a prayer, but now it's all about Ruiz and I believe Ruiz does exactly the same the second time around and then Ruiz takes his place as the three-headed monster.
"I thought Ruiz won every round in that fight. It wasn't a fluke punch like Hasim Rahman and Lennox Lewis. In the rematch, Lewis turned up and didn't get hit with a punch and knocked him out.
"He [Joshua] clearly lost the rounds -- he was getting outboxed, he was getting outfought and then he got knocked down three times to boot."
Fury also spoke about his own potential rematch with Deontay Wilder, which finished as a controversial draw last year.
He said: "The mistake I made last time, which I won't make again, was believe that it will be a fair playing field because we know it isn't going to be, so I must knock him out.
"I don't believe I can get a points victory over here because I clearly won that last fight. I outboxed him every round other than the two he knocked me down in.
"It's clearly not possible for me to get a points victory so I have to change my style, which I'm happy with because I've never been as strong, never punched as hard, I've never been as confident as I am today. I am going to knock him out this time.
"I'm not going to tip-tap around boxing because we know where that got us last time don't we so I believe it's going to be him or me [getting knocked out]."
