WBO, IBF, WBA, IBO heavyweight world champion Anthony Joshua is hoping to land a unification in 2020.

Joshua is ending off 2019 on a very high note.

Back in June, one of the biggest upsets in the history of the heavyweight division took place when Joshua was stopped by Andy Ruiz in seven rounds. Joshua redeemed himself earlier this month, when he outboxed Ruiz over twelve rounds to reclaim his four belts in Saudi Arabia.

In the last few years, there has been a lot of hype for a potential showdown between Joshua and WBC heavyweight champion Deontay Wilder.

They have traded words on more than one occasion, the two are big punchers - but Joshua indicates that it's Wilder's belt that draws him to the fight.

"It’s not so much stylistically or so much of a grudge, it’s just that I’ve got four of the belts and I want the last one, so Deontay Wilder would be my preference," Joshua told RT.

"Honestly, since I’ve been back it’s been two weeks and I haven’t even had a chance to think of let alone my New Year’s resolution, let alone who I’m going to be fighting next.

"Whoever’s the better opponent would be ideal for me, I’m not too fussed. If you look down the record we’ve fought champions, great fighters, so another one on that list would be an honor for me because I think it builds legacy. I don’t really shy away from a challenge so whoever steps up first will definitely get the opportunity to try and take my belts."

Wilder has a rematch scheduled for February 22, when he faces Tyson Fury. They fought to a controversial draw n December 2018.

And Joshua has two mandatory obligations at his feet. The IBF have ordered him to face Kubrat Pulev, while the WBO has issued an order for a mandatory fight against Oleksandr Usyk. At the moment Pulev appears to be the frontrunner.
