It’s heavyweight boxing.“Wladimir Klitschko lost to Ross Puritty, no-one even knows that guy. There’s a case for both guys winning this fight, I think. Both guys showed a lot of versatility in their fights.“[Joshua’s] two fights with [Andy] Ruiz and [Fury’s] two fights with [Deontay] Wilder – they’re the same guys but they’re different styles and different ways of getting the victory.“Joshua had a loss against Ruiz, Fury had a draw against Wilder. Then Fury came off the back foot, was aggressive and knocked Wilder out. “And Joshua came off the front foot, got on the back foot and got a points decision against Andy Ruiz.“You see what I’m saying? It’s hard, only true fans of each guy will say, ‘This guy’s gonna win.’ It’s very hard, I don’t think no boxing purist would say, ‘This guys gonna win because of this.’”AJ beat Dillian Whyte at The O2 in 2015Credit: GettyThe Body Snatcher was brutally stopped by the Gypsy King with an upper cutCredit: GettyWLADIMIR KLITSCHKO The legendary Ukrainian suffered a huge upset when Fury beat him in Germany in November 2015 on points to become heavyweight champ.Klitschko and Joshua then produced a classic in front of 90,000 fans at Wembley seventeen months later as both stars hit the canvas in the rollercoaster clash.It was eventually AJ that delivered the finisher, knocking the veteran down tice in the 11th which resulted in the ref stopping it.And Klitschko has no doubts who would win out of AJ vs Fury, saying: “Hands down Joshua.“He is getting to be the complete fighter. Technically, size-wise, weight-wise, power-wise. And he is a good learner. The other guy [Fury], like a fart in the wind it is there and it is gone. “In the history of boxing there are a lot of examples of this kind of guy. They can be successful for a time but are not disciplined enough to continue to be successful.“I wish Tyson well but I think there is a lack of discipline there, and discipline is more important than motivation. “Drawing from my experience I would say it is going to be very difficult for Tyson because there’s that lack of discipline.”Tyson Fury shocked the world back in November 2015 against Wladimir KlitschkoCredit: ReutersAJ and the Ukrainian produced a classic at Wembley in 2017Credit: GettyOTTO WALLINThe Swede was only meant to be a tune-up for Fury ahead of his rematch with Wilder in 2019 but he almost caused a huge shock.He caused a huge gash above the Gypsy King’s right eye that almost caused the doctor to step in, only for Fury to bravely battle on and get the decision before heading to hospital to receive 47 stitches.But AJ suffered no scares against Wallin on December 23 at Day of Reckoning in Saudi Arabia as he dished out so much punishment that his rival’s corner was forced to throw in the towel after the fifth round.On a potential fight between the Brits, Wallin said: “Well, I would say that this fight with Joshua was a lot tougher than the fight I had with Fury. “It’s hard to say [what would happen in a fight between Fury and Joshua]. I think that Fury’s a very good fighter. Can probably pick it up from what he was doing in his last fight.“It’s a decent fight. We’ll see what happens with Joshua now.“He might be on to something really good with Ben Davison, and Ben obviously knows Tyson. I don’t know. There’s a lot of variables.READ MORE SUN STORIES“I always said that Fury would win that fight, but now just being in with Joshua, I feel a little bit different.“It’s hard to go against Tyson I think.
