Nick Kyrgios has confirmed he has no plans to work with a full-time coach during the 2018 season.
The world number 20 worked alongside Sebastien Grosjean on a part-time basis this year, but he is currently without any kind of trainer and he believes that will suit him fine heading into the New Year.
"I haven't got a coach and I think I'm just going to go about my thing the same way that I did this year," he said. "I've pretty much done it all alone the last three years to get to a career high of 13."
The 22-year-old endured a mixed 2017, as he failed to make it beyond the second round of a Grand Slam event, while injury brought his season to a premature end.
The Australian did, however, reach the final of the Cincinnati Masters in August and he is confident he can continue to progress even if he remains without a coach for an extended period of time, as he does not believe outside influences always have his best interests at heart.
"To bring someone on, it's tough to know whether they're just doing it for the sake of getting a bit of cash or rather have best interests at heart," he added. "I'm not looking for someone who has a big name or anything, it's more trying to find someone who has my best interests and I can confide in."
Kyrgios is expected to face a busy start to 2018, as he has already signed on to headline a Tie Break Tens event in Melbourne alongside Novak Djokovic, before he will then turn his attention to next month's Australian Open.
