Anthony Joshua teases fans with video clip of spar with Wladimir Klitschko in 2014 years before Wembley fight

Anthony Joshua has teased fans this week by sharing a video clip from a sparring session he had with Wladimir Klitschko.
Three years before the pair met in their infamous Wembley Stadium battle in 2017, Klitschko brought a young AJ out to his training camp in Austria.
Wladimir was preparing for his defence against Kubrat Pulev at the time and asked Joshua to help him get ready.
The Brit was in the early stages of his professional career and so used the experience to gain knowledge on how a heavyweight world champion conducted his training.
Klitschko made a prophetic prediction when he spoke after having AJ in camp.
He told : "If he is going to keep doing what he is doing, he will be champion for sure.
"I think he has amazing potential. He needs to learn, but that will come.
"I think he has the size and the weight. He's built like a modern professional warrior and athlete.
"He has good technique and good amateur background, which is important.
"He is an Olympic champion, but he doesn't carry himself as Olympic champion like, 'I'm so cool.'
"He is very humble. He learns. He asks a lot of questions and he is very open-minded and wants to learn. I enjoyed having him in camp."
Joshua added at the time: "I felt I belonged there, but Wladimir is different to everyone else.
"He has been the champ for years. He's in a league of his own.
"For me to be where Wladimir Klitschko is, there's a lot of work to be done.
"I can see myself potentially being there, but to own it and make it look easy, there's a little bit of work to be done.
"I feel I am talented enough to become the world champion, but to stay there for as long as he has, keep defending the titles and stay hungry for it, that's what I need to learn."
