Nick Kyrgios is one of the most unpredictable and controversial tennis players the sport has ever produced.
The Australian has rarely been seen on the ATP Tour in 2025, although Kyrgios is expected to face Aryna Sabalenka in the Battle of the Sexes in 2026.
At his best, Kyrgios is one of the most dangerous players on the circuit but injury problems have plagued him over the last few years.
The star’s volatile nature has meant he’s gone without a coach since 2017, and he’s revealed why he split from Sebastian Grosjean in the same year.

Nick Kyrgios explains why he split with Sebastian Grosjean
Kyrgios appeared on a roundtable with Jeremy Chardy and Richard Gasquet and the Australian explained the behaviour which led to his split with Sebastian Grosjean.
The former world number four worked with Kyrgios in 2017, but their working relationship did not last very long.
On the UTS Tour’s Instagram video, Kyrgios said: “I’m uncoachable bro. I had Seb [Grosjean] for a bit. Seb was amazing, but then I was crazy at that time, and I felt bad because he was so nice.
“One day I was good, one day I was bad. I felt sorry because he was so good, so dedicated. I was like, ‘I feel bad, go and coach someone who is going to listen to you all the time.
“I’m so unpredictable. I’m actually crazy. Off the court, I’m f—— crazy. I’ll go missing for two days.”
Kyrgios has worked without a coach since splitting from Grosjean, despite several high-profile former players offering their services to him.
The likes of Jimmy Connors, Pete Sampras, and John McEnroe have all offered to work with Kyrgios throughout his career.
Why Nick Kyrgios has not hired another coach since Sebastian Grosjean
The Australian has been playing without a coach for nearly a decade now and he explained his reasoning in 2020.
Speaking to TNT Sports, Kyrgios said: “To get a coach for me is just pointless. Because I don’t want to waste their time almost.
“I just don’t think a coach is ready – and I’m not going to put them through it too cause it would just be a nightmare.
“Where I’m at my career now, it’s just too far gone, I think for a coach, ’cause I’m too set in my ways and I just don’t like to listen to advice, to be honest.”
The Australian has reached a Wimbledon final and won the Australian Open doubles title without a coach, so Kyrgios is clearly doing something right without expert guidance.
