Nick Kyrgios says tennis coaches get paid too much, and he's too set in his ways to ever need one anyway.
And in line with his status as a modern sports anti-hero, the outspoken Aussie has told a podcaster that winning grand slams is not his goal.
Kyrgios, ranked 40 in the world, also wishes he had played in a bygone era when the game had more characters.
The gifted Kyrgios polarises opinion around the world. But at his best he is an artist on the court, with an outlandish personality which attracts a lot of fans.
Kyrgios implied he would feel bad about putting a fulltime coach through the ringer.
