IBF, WBO, WBA, IBO heavyweight champion Anthony Joshua is aiming to add to the legacy of his career with defining fights in 2020.

Last month, Joshua became a two-time champion when he reclaimed his four heavyweight titles with a dominant twelve round unanimous decision over Andy Ruiz. The contest was rematch of their June encounter, where Ruiz dropped Joshua four times to secure a seventh round stoppage at New York's Madison Square Garden.

"We created history by becoming a two-time champion of the world and I feel like we can add to that legacy in 2020," Joshua told Sky Sports.

Joshua is now under order for two mandatory defenses.

The IBF have ordered him to face Kubrat Pulev, while the WBO have issued an order to have him face Oleksandr Usyk. At the moment Pulev appears to be the frontrunner. Joshua's next return should come down on a date in April or May.

Joshua explained that he's not the type to overlook any opponent that he faces in the ring. And two of the attributes that he credits for his years of success, is his dedication and mental strength when entering the ring for a big fight.

"It's all fun and games in the gym but then you walk down the aisle to the ring and you think, what if I just turn back and I said I just can't do this….you've just come too far to turn back so you just have to deal with the anxiety," Joshua said.

"How do you channel that responsibility and pressure? Dedication. When you're dedicated to yourself, you can be dedicated to anything. I am a fighter. Even when I stop fighting I'll always have that passion. I don't really put on that face for fighting and then another face for outside of the ring."
