Heavyweight contender Otto Wallin is very confident of pulling off a shocking upset over former two-time world champion Anthony Joshua.

Their fight will headline a big card on December 23rd in Saudi Arabia.

In the co-feature, Deontay Wilder will battle Joseph Parker in a showdown of former champions.

Should Joshua and Wilder both prevail, there is a good possibility of them colliding in 2024.

However, Wallin believes Wilder has a very dangerous fight on his hands as well. Wilder has not been very active, with only a single round of action since 2021. Parker will be taking part in his fourth fight of the year.

While some view Wallin as a legit threat in the fight, former super middleweight champ Carl Froch is not in favor of the match. He would have much rather seen Joshua and Wilder skip the interim-bouts and go immediately to their showdown. 

"Carl is going to be disappointed when AJ loses. I understand where Carl Froch is coming from. They want to see Deontay Wilder and AJ, which would be a really big fight, but I'm really excited about this fight. That's all that matters. Me, my team, my family, we are all really excited," Wallin told Vegas Insider.

"When AJ loses, the Wilder fight is not going to be as big. Who knows with the Wilder vs. Joseph Parker fight? That's also a good fight. Parker has been staying active, while Wilder hasn't. That's a good fight and not an easy fight for Wilder. 

"Imagine if both Wilder and AJ lose; obviously, they can still fight each other, but it won't be as big of a fight.
