Nick Kyrgios just won’t give in as his Twitter spat with Borna Coric continued yesterday, with the firebrand Aussie telling the Croat he was a ‘boring peanut-brain who brings zero to tennis’.

The pair have been locked in a war of words for a few days over Kyrgios’ criticism of the behaviour of players on the Novak Djokovic Adria Tour.

“Really, Nick Kyrgios?” Coric asked on Twitter. “You’re preaching about behaviour?? Bored much or too much [wine]?”

The Aussie was in no mood to accept that.

“Again, joking about a global pandemic,” Kyrgios replied to Coric.

“Shows your maturity level champion. Gonna be good to see you next, see if that peanut of a brain has grown.

“But yes, a tad bored watching your boring ass tennis and personality bringing absolutely zero to the sport.
