Nick Kyrgios says he is no longer driven by rankings or trophies, admitting he has been a “chaotic mess” throughout his career and now simply wants to enjoy himself as he returns to the ATP Tour this week.

The mercurial Australian, a Wimbledon finalist in 2022 and one of tennis’s most electrifying talents at his peak, makes his comeback at the season-opening Brisbane International.

Now 30, Kyrgios has slipped to world No. 671 after an injury-plagued three-year period in which he played just six ATP Tour singles matches. Speaking ahead of his opening-round clash, he said he feels fit and as sharp as ever following an encouraging build-up.

“After every injury I’ve had over the last couple of years, and seeing how quickly things can be taken away from you, I’ve developed a day-by-day mindset,” said the former world No. 13.

“I don’t think I’m a player who needs to prove himself anymore. I just want to get through this and be happy with my performance.

“Ultimately, I want to go out there and put on a show for the crowd — for the fans and the people. I have no agenda. I don’t care what my ranking is or what titles I win.

“I just want to give people a good show. That’s probably what I’ll be remembered for — an entertainer, someone who was a bit of a chaotic mess, but an entertainer at the end of the day.”

Kyrgios, who received a wildcard entry into the Brisbane International, begins his return against American world No. 60 Aleksandar Kovacevic.

While his appearances on tour have been sporadic in recent seasons, he showed flashes of his enduring ability last week by defeating women’s world No. 1 Aryna Sabalenka in a “Battle of the Sexes” exhibition match in Dubai.

He could yet also be offered a wildcard for the singles draw at this month’s Australian Open.

“Considering how much travel I’ve done in the last month and how much tennis I’ve played, this is about as good as I could feel,” Kyrgios said.

“A lot of stress has gone out of my life and I feel much better. My goal is to leave Brisbane feeling like it was a fun week — that I gave everything I had and put on a good show, whether I won or lost.

“I’m just really looking forward to competing at the highest level again. At this point, it all feels like a blessing.”
