WBA/IBO/WBO/IBF heavyweight champion Wladimir Klitschko has tipped Britain's Anthony Joshua to become a future star.

Klitschko, who faces fellow Brit Tyson Fury in October in his world heavyweight championship title defense, has revealed he has never seen anyone with such potential as Joshua.

The 25-year-old, an Olympic champion from the 2012 Games, has won his first 13 fights since turning professional.

And, Ukrainian superstar Klitschko believes the Londoner is destined to become a great champion.

"I've faced a lot of athletes and opponents and in the last 25 years there is one person who has the potential to become a really big star in boxing," Klitschko told BBC Radio.

"Not only inside the ring but that person, and I'm talking about Anthony Joshua, has qualities that not many guys have had.

"Either they had good skills but not the strength, or they had strength but not the skills.

"Or they were good inside the ring but not outside because their life outside messed them up and that reflected on their sporting career.

"I think Anthony has all the tools to become the great champion inside and outside the ring."

Klitschko even went as far to not rule out meeting Joshua before the 39-year-old hangs up his gloves.

"I think he needs to improve and move forward but eventually it can happen if I stay where I am today," he added.
