Oleksandr Usyk has his sights firmly set on fighting Britain's boxing sensation Anthony Joshua when the Ukrainian cruiserweight moves up to heavyweight, once he himself has proved that he is the best in the world in his current division.

Usyk himself is currently a big star and is the number one seed right now, and is preparing to take on Mairis Briedis in the World Boxing Super Series semi-final, perhaps facing one of the toughest, if not the toughest opponent, of his career.

He hasn't really looked at who he will fight beyond Briedis in order to keep his focus on his next opponent, but he has admitted he will fight Joshua at some point down the road.

"I will, but let's wait for a while," he 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."

Joshua and Usyk have fought in the same event before, the pair of them taking home Olympic gold in the 2012 Olympic Games in London.

Usyk got a great reception at the event and he has a lot of respect for the United Kingdom, particularly the heritage it has in boxing with our island being where the sport originated from.

"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," said Usyk.

Joshua himself has a big fight coming up in the not too distant future.

He is set to face Joseph Parker at the Principality Stadium in Cardiff on March 31 in the world heavyweight title unification fight.

Meanwhile, Usyk is gearing up for his fight against Briedis and he is under no illusions about what he is up against.

"I do think Briedis will be the toughest opponent I have faced in my professional career," he said.

"He is 23-0, he's a cruiserweight and he can punch and that makes anyone dangerous. You are going to see my boxing, everything I do week, once I am in there with him."

The fight takes place this coming Saturday and it is certain to be a real spectacle!
