Anthony Joshua regained his three heavyweight world titles after defeating Andy Ruiz Jr. in their rematch in Saudi Arabia.
The WBO could force Joshua to face mandatory challenger Oleksandr Usyk to defend his titles.
Many fans wanting a fight between the Brit and the winner of Tyson Fury and Deontay Wilder may have to wait with Joshua having to get in the ring at least once more before a potential agreement.
IBF mandatory challenger Kubrat Pulev is another potential opponent for the 30 year-old next year.
Following the victory against Ruiz Jr, Joshua talked to BBC Sport following the fight about a potential encounter with either Fury or Wilder:
“Once their rematch is out of the way they can start mentioning my name,
“I can’t keep on fighting all the champions, the best in the division and then other people who say they want to step up don’t step up.
“All challengers are welcome to take on this current unified champion.”
Fury and Wilder rematch is on Feburary 22, in Las Vegas after the two drew their first fight.
There has also been talk of Joshua’s first fight of 2020 being against former opponent Dillian Whyte.
Whyte had a doping charge dropped by UK anti-doping before going on to beat Mariusz Wach on the undercard for Joshua’s fight on Saturday.
Joshua beat Whyte back in 2015 after a seventh round knockout at the O2 arena in London to claim the British heavyweight title.
There has always been a rivalry between the two since Whyte beat Joshua in an amateur bout in 2009.
The defeat to Joshua is still Whyte’s only loss to date.
