WBO cruiserweight champion Oleksandr Usyk (13-0, 11 KOs) is planning to eventually challenge WBA, IBF, IBO heavyweight champion Anthony Joshua (20-0, 20 KOs) in the future.

Both boxers won Olympic gold medals at the 2012 London games (Usyk at heavyweight, Joshua at super heavyweight). Both boxers won their first world title in 2016, and now both of them have a scheduled unification coming up.

Usyk is in action this Saturday, when he faces WBC cruiserweight champion Mairis Briedis in the semi-finals of the World Boxing Super Series, in Riga, Latvia.

If Usyk wins, he will then face the winner of next month's WBA, IBF title fight between Yunier Dorticos and Murat Gassiev.

Should Usyk win the tournament and walk away with all four of the cruiserweight titles, the next move would be a jump in weight to the heavyweight division.

And that's where he will target the biggest name in the division, Joshua.

Usyk, who was part of the same talented Olympic squad as Vasyl Lomachenko, is regarded as one of the best boxers in the sport. Last year, he passed his first WBSS test by stopping former world champion Marco Huck.

He believes that his real legacy will be made in the heavyweight ranks, when he showcases his skills against the big men.

"I will [fight Joshua] but let's wait for a while," Usyk exclusively told Sky Sports.

"I will move up to heavyweight and show them all how good I am. I think you can see yourself, I will fight him (Joshua). Not yet though. But it is a question everybody keeps asking me [on when will I fight Joshua], so once we go face to face, we will find out. It will be good. First of all, I like Britain because that is where boxing was born. The fans over there still follow me and watch me, so I will always try and show them my best."
