Anthony Joshua retained his WBO, WBA and IBF titles after he beat Andy Ruiz in his rematch in Saudi Arabia.
Ruiz beat Joshua in June but the British boxer fought all 12 rounds of their rematch to win the fight on points.
AJ has already turned his attention to who he will take on in the future.
Mandatory challengers Oleksander Usky (WBO) and Kubrat Pulev (IBF) are in the top of the list of potential opponents.
Speaking to Sky Sports, on Usyk
, Joshua said: “He's from a great school of boxing, the sweet science of boxing, about hitting and not getting hit. I study Usyk so know his weaknesses and his strengths, that's a competition I'm looking forward to."
Joshua also spoke about Pulev
: "He comes from a great background of amateur boxing and comes from a boxing family, his brother boxes as well. He's soon to be one of my mandatory challengers."
After finishing his business with mandatory challengers, Joshua could go after either Deontay Wilder or Tyson Fury for a unification fight.
, Joshua commented: "He's very talented, they brought him up wisely and let him gain a lot of experience which I think every fighter needs. Once you cross over to world championship level, there's no coming back.
"Even though it's taken Wilder more fights than myself, when he's crossed over he's never looked back. His success and his route to success has worked out perfectly for him, congratulations to him and his team."
Joshua also gave his opinion on the 'Gypsy King' Fury
, saying: "He takes inspiration from Muhammad Ali. He talks a good game, fights a good game, he's a talented heavyweight boxer."
Finally, on former WBC interim heavyweight champion Dillian Whyte
, Joshua added: "Dillian's done well and he's cleared his name of any allegations and issues he's had. He's a warhorse, Brixton-mafia, strong, ready, and I'm ready to get it on again."
