Britain's world heavyweight champion Anthony Joshua has apparently taken on Sir Alex Ferguson’s old winning mentality to stay at the top.

The secret behind Fergie's successful reign at Manchester United was always all about the 'next game', and it seems Joshua is just as driven after talking with former United and England star Rio Ferdinand about how he managed to stay hungry.

“I was speaking to Rio Ferdinand and that’s what he was saying about always looking to what’s next,” said the unbeaten world heavyweight king.

“He said the mindset at Manchester United was, 'What’s next?'

“He said he would win a big game and everyone would be celebrating and he would be speaking to the gaffer and saying ‘What’s next? Who have we  got?’ The mindset was to keep pushing on — what’s the next game? What’s the next trophy?"

Joshua says that he has this same mindset in boxing.

“That’s the winning mindset Sir Alex Ferguson instilled in them. I think that’s instilled in me too. It’s just who I am. That winning mentality is just me in life.”

Although Joshua's victory over Wladimir Klitschko in April will be a lasting memory for the boxing star, he knows that he needs to move on and focus on defeating Carlos Takam this weekend to defend his WBA Super and IBF belts.

No heavyweight in history has ever held all four major titles simultaneously, so Joshua immediately set that as his goal, and it could be realised by the end of next year if he can land fights with WBO champ Joseph Parker and WBC king Deontay Wilder, with the help of promoter Eddie Hearn.

Joshua said: “Even though the Klitschko fight was great, I’ve got to forget it and move on. I can’t keep looking back at it. It’s gone.

“I can’t go out and perform badly against Takam and say, 'It’s OK because I did so well against Klitschko.' That’s not how you progress.

“Takam is all I’m thinking about because he’s my next fight. I will definitely have more big fights in my career, but I have to take care of Takam first."

The 28 year-old has said he gets his single-mindedness from his dad Robert, who remains a big part of his life, even though he lives in Nigeria.

“Yeah, I get that mentality from my dad,” he said. “My dad is the boss, big Josh.”

Joshua will step into the ring under the closed roof of Cardiff’s Principality Stadium on Saturday night with the intention to entertain the record 78,000 crowd.

He knows they are expecting stoppage number 20, and we know Joshua won't disappoint.
