Nick Kyrgios sparks Australian Open controversy by telling umpire: "You are terrible"
Nick Kyrgios has lived up to his reputation as the most controversial player in men's tennis with another outburst at the Australian Open.
Kyrgios was embroiled in a row with the umpire during his third-round defeat to Tomas Berdych on Rod Laver Arena.
The 20-year-old was angry after music started playing in the crowd during the second set of his 6-3, 6-4, 1-6, 6-4 defeat to the Czech Republic player.
He was heard shouting at the umpire: "Mate, are you okay? There's music playing in the crowd while we are playing! I've told you seven times! Mate!"
"Am I hearing things? Am I hearing things? Mate, it's a circus."
Kyrgios bounced back to win the third set but succumbed in the fourth, and duly unleashed another volley at the umpire on his way out.
After losing the match on a double fault, he told the umpire: "You are a terrible referee."
Kyrgios has become the pantomime villain of the ATP circuit with his frequent outbursts and bad behaviour on court.
Most notoriously, he sledged Stanislas Wawrinka over his then girlfriend - the fellow tennis player Donna Vekic - at the Montreal Masters in August 2015.
At the time, Wawrinka said: "Every match he has problems. Every match he behaves very badly.
"On top of that the problem is that he doesn't just behave badly towards himself he behaves badly toward the people around, the other players, the ball kids, the umpires."
