Nick Kyrgios has revealed his strong dislike for "cringeworthy" Novak Djokovic and "super salty" Rafael Nadal.
The outspoken Australian gave a candid interview to the No Challenges Remaining podcast in which he opened up about his attitude to tennis and his fellow players.
Kyrgios reserved his strongest words for world number one Djokovic and vowed to imitate the Serbian's celebration, in which he throws his arms out to the crowd to show his love.
"I just feel like he has a sick obsession with wanting to be liked," said Kyrgios about Djokovic. "Like he wants to be like Roger (Federer). I just can't stand him. This whole celebration thing he does after matches, it's so cringeworthy.
"He's a champion of the sport, one of the greatest we'll ever see. I honestly think he will get the grand slam count (for most titles in history), he'll pass Federer.
"No matter how many grand slams he wins, he will never be the greatest for me simply because I've played him twice and, I'm sorry, but if you can't beat me, you're not the greatest of all time.
"If I play him and I beat him, I'm doing his celebration in front of him. That would be hilarious."
Kyrgios also accused Nadal of being a sore loser and labelled his uncle and long-time coach Toni an "idiot".
Nadal claimed Kyrgios lacked respect after losing to him in Acapulco in February, with the Australian attempting an underarm serve on his way to victory.
Kyrgios, who also described Nadal's Spanish countryman Fernando Verdasco as "the most arrogant person ever", said: "He's my polar opposite. And he's super salty.
"When he wins, it's fine, he won't say anything bad, he'll credit the opponent. But as soon as I beat him it's just like he has no respect for me, my fans, and no respect to the game.
"And then uncle Toni came out saying, 'he lacks education'. I'm like, I did 12 years at school you idiot. I'm very educated. We do things differently. Why can't we just accept that?"
