The 30-year-old Australian - who has played just five singles matches this year due to injury - beat the women's world number one 6-3, 6-3, in a Battle of the Sexes exhibition match in Dubai, and despite taking just 70 minutes to see off his opponent, he insisted it was a "really tough" game and he'd love to play Aryna again.

He said: "Honestly, it was a really tough match. She's a hell of a competitor and such a great champion. Obviously, she's a multiple Grand Slam champion.

"I didn't really know what to expect. She broke my serve numerous times. Honestly, I had to strap in because she was putting the pressure on. She was hitting some amazing shots.

"Honestly, I would love to play her again and showcase her talent and also what I have left in the tank. Ultimately, it was a really hard-fought battle. There were breaks back and forth.

"I wouldn't call myself the champion tonight - seeing someone as great as Aryna out here and myself, I think it truly was a spectacle. I think this is a great stepping stone forward for the sport of tennis.

"Of course, I was nervous. I don't think many people would have put their hand up to be in this position, especially in my position. Aryna was up for the challenge and the scoreline was closer than it was."

The Belarussian is also keen for a rematch because she knows Nick's game better now.

She said: "I felt great. I think I put up a great fight and he was struggling. I think it was a great level. I made a lot of great shots, moved a lot to the net, had great drop shots.

"I really enjoyed the show and I feel like next time - when I play him - I already know the tactics. I know his strengths, his weaknesses and it's going to be a better match for sure.

"I love to challenge myself and I would love to play again. The court is different - I had to do a couple adjustments. Obviously playing against a guy is completely different tennis and everything is much faster. It was great fitness for me today."
