Former UFC champion Michael Bisping has predicted Tommy Fury will be in for a tough night against Jake Paul.
Paul and Fury will meet in Miami on December 18 after months of teasing a fight on social media.
The two fought on the same card in August when Fury defeated Paul's sparring Anthony Taylor and Paul outpointed former UFC star Tyron Woodley.

Fury had turned down a £1 million fight offer from Paul, with the internet star later offering an additional $500,000 bet that Fury must change his name to Tommy 'Fumbles' if he loses.
The Brit accepted the offer as the two men will settle their differences a week before Christmas but Bisping - who was ringside for Paul and Fury's last fights - has backed the YouTube star.
He said on his YouTube channel: “Listen, Jake Paul isn’t just a YouTuber. He’s a boxer. He used to be a YouTuber, probably still is one, but he’s also a boxer.
"Just because you discover your love for the sweet science later in life doesn’t mean you have to be labelled a YouTuber your entire life. The reality is Jake Paul is doing a lot of great things in the boxing world.

“I thought it was a bad night at the office for Tommy Fury against Anthony Taylor. I thought he didn't look very good. A guy that's not a boxer, way smaller than him and realistically Tommy Fury should have finished him.
"Some of his other fights he looked explosive, powerful, aggressive. Against Anthony Taylor I didn't see those.
"If he struggled against Anthony Taylor, he’s going to struggle against Jake Paul. That’s just my two cents, and I believe that he loses.”
Early odds have given the more experienced Fury a slight edge to defeat Paul.
Paul is undefeated in four professional fights whilst Fury turned pro in 2018 and has since gone 7-0.

WBC heavyweight champion Tyson Fury - who is Tommy's brother - vowed to retire Tommy from the sport if he can't get past Paul.
But Bisping doesn't think Fury will retire or change his name to Tommy 'Fumbles' if he loses the fight.
"I think Jake Paul goes out there, he beats Tommy Fury. I don't think Tommy Fury's gonna retire. I guarantee he doesn't even change his name to Tommy 'Fumbles' I mean he should do. If you take a bet you've gotta be a man of your word," he continued.
"You know why? Because Jake Paul told Tyron Woodley to go f*** himself on their bet. They were in the ring and Jake Paul said I'll do the rematch if you get 'I love Jake Paul' tattooed on you.
"Tyron did it and Jake Paul isn't doing the rematch. Point I'm making is if Jake Paul can not honour his bet, so can Tommy 'Fumbles'."
