Kyrgios hits back at Wawrinka criticism

Young Mr. Kyrgios has a lot to learn !

I suspect he didn't think to apologise to the girl whose name he dragged through the mud.

No doubt the ladies on tour will stay away from this piece of trash, and his friend Kokkinakis who has a pair of slightly loose lips himself.

If tennis doesn't work out, he could put that haircut and personality to work doing remakes of 1970s Bobby DeNiro films.
