Nick Kyrgios on Sunday credited four-time Grand Slam winner Naomi Osaka for helping him to deal with his inner demons.

After the Australian produced a clinical display to dispatch Italy’s Fabio Fognini in the third round of the Masters 1000 tournament in Miami, he once again opened up about the mental struggles he had endured over the past few years.

Kyrgios said he had moved on from the “dark places” in his life and had found a kindred spirit in Osaka, who has blazed a trail on the topic of mental health in sport.
