Kyrgios is a yobbo, and an embarrassment to Australia.

Agree with ttbn, the guy has a serious attitude problem.
I'm ashamed he represents us, he needs to grow up.

All he needs is a laser like focus and he's the best tennis player in the world! And that means he needs to learn self discipline and as others try to upset/distract him, all the more reason and motivation to answer with his play and the scoreboard results! And I'm not saying that will be easy! But nonetheless necessary!

Agree with AB.

I think he knows exactly what he's doing.
It attracts the publicity he's after - and
the crowds. Just like McEnroe used to do.

He livens up the game with people waiting to see
what he does next. Will he or won't he yell
at the score keepers, or the crowds, or even his
own supporters? It makes the audience something
else to talk about and look forward to.

It's amazing the change that comes over him when
he's off the courts and being interviewed.
Right?

So, this Kyrigios bloke is very good at returning balls aimed at him from across a net? Big deal. He is also an arrogant narcissist
who is an embarrassment to Australia. One hopes he will renounce his Australian citizenship and return to his ethnic homeland where his disgusting behaviour is considered normal.
