Nick Kyrgios Hits Back at Stanislas Wawrinka Criticism

Australian bad boy Nick Kyrgios fired back at Stan Wawrinka on Thursday over suggestions he had not apologized for his lurid outburst towards the Swiss star.

Wawrinka criticised Kyrgios on Wednesday after stating he had not made a proper apology for crude remarks concerning the Swiss star's reported girlfriend, teenager Donna Vekic.

"He didn't really apologise to the people. He should. That's it. That simple," Wawrinka told reporters in Cincinnati.

Kyrgios triggered widespread revulsion for his on-court taunt to Wawrinka last week that fellow Aussie Thanasi Kokkinakis had had a fling with WTA professional Vekic.

However Kyrgios, who was fined by the ATP for his remarks, insisted on Thursday that he had made private and public apologies following his outburst.

"I am not trying to take any more attention away from the matches in Cincy, but I have been reading reports that I did not apologise for my comments, which is untrue," Kyrgios said in a statement posted on Facebook.

"I privately and publicly apologised immediately after the match last week.

"There is no blame game, I take full responsibility for what was said and for what has been a difficult learning experience," he said.

In remarks made to a Canadian newspaper earlier this week, Vekic, 19, said she had not received any communication from Kyrgios over the incident.

"I haven't spoken to Kyrgios. But it's a very disappointing thing to be happening in our sport and I hope it won't happen again because it's not a very good image for our sport," she said.
