Outbursts and fits of rage have seen Nick Kyrgios involved in some shameful on-court scenes over the years, but the tennis star's "embarrassment" was saved for another person this week.
That's after the world No. 76 uploaded a selfie where one of his fellow gym-goers was the focus. An instructor, no less, as he surreptitiously snapped a shot of the man in question training topless indoors.
"Only in Australia at a national academy and a ‘coach’ / ‘staff’ is in the gym with his shirt off," Kyrgios wrote to his 474,000 Twitter followers. "Haha these are the people that are supposed to be guiding our youth. I’m embarrassed for real."
