As a surprise to not many, Nick Kyrgios let his feelings be known after defeating foe Casper Ruud at the Indian Wells tournament on Tuesday.
The feud between the Aussie tennis larrikin and the Norwegian athlete began years ago, after Ruud labelled his opponent an "idiot" for throwing a chair onto the court during an Italian Open match.
Ruud called for Kyrgios to be banished from the game, which fired up the Australian on social media.
"I would appreciate you saying it to my face. I’m sure you wouldn’t run your mouth so much after that," Kyrgios said in a tweet following the 2019 match.
In the first appearance since their saga in Rome, Kyrgios was clinical defeating the 8th-seeded Ruud 6-4, 6-4 to advance to the final 16 players of the ATP masters event.
