In his recent tweet, Nick Kyrgios responded to Borna Coric who said that he doesn't care about his opinion.

After the second leg of the Adria Tour was cancelled due to some players being tested positive for COVID-19, many tennis players reacted to the happening of this tournament. Nick Kyrgios was one of the loudest voices as the Aussie was really critical about the tournament. In the recent interview, Borna Coric, who was one of the participants, said that he 'doesn't care about Kyrgios' opinion'. Now, the Aussie reacted on his Twitter when he wrote:

"You should care. Do you have rocks in your head? Again, you can stand up for your mates, I’m just trying to hold them accountable. When I said what I said, I didn’t intend to bother. They are tennis players, they aren’t special. Just as I thought Coric intellectual level = 0"
