Anthony Joshua has furthered his boxing education by sparring with world heavyweight champion Wladimir Klitschko this week.

Watford’s Joshua, who is unbeaten in seven fights as a professional – winning each by knockout – attended Klitschko’s training camp as the Ukrainian prepares to put his WBA, IBF and WBO belts on the line against Kubrat Pulev on September 6.

Speaking on Sky Sports News, Matchroom Sport promoter Eddie Hearn said the experience of sparring with 38-year-old Klitschko was “priceless” for Olympic gold medallist Joshua.

“To mix with the likes of those guys, not just in the ring, just to be around them, see how they conduct themselves in terms of their diet, their demeanour from the commercial and PR perspective as well,” said Hearn.

“It's a fantastic opportunity for Anthony to go out and spar with Wladimir and you’re talking about a top, top fighter in Anthony Joshua.

“He’ll certainly find it tough, going in sparring with Wladimir – I’m sure there are not many that don’t – but he’ll come back a better fighter.”

Joshua returns to the ring on September 13 at the Manchester Arena before taking on Michael Sprott (42-22) at the O2 Arena in London on October 11.

The 24-year-old kept up his record of winning by stoppage in his most recent bout, beating former world title challenger Matt Skelton in the second round at Liverpool’s Echo Arena in July.
