Nick Kyrgios

Federer: Kyrgios no chance of winning Australian Open

Federer, who has claimed four Australian Open titles himself, believes Kyrgios isn't experienced enough to go the full length.

"To win, he drops, in my humble opinion,'' Federer told Fairfax Media

''To do anything, yes, first week no problem, but to go all the way it's a long way, and he's never been into a semis before, so first he has to prove to the world and himself that he can make the semis.

"So for me to start talking about him winning the tournament, Lleyton [Hewitt] never did it, and he was two times world No.1 at the end of the year.

Wimbledon: Nick Kyrgios in heated row with journalist

The Australian 15th seed received a warning from umpire Jake Garner at the start of the third set after complaining about a decision and he completely lost his head before reaching the third round with a 6-7(3-7), 6-1, 2-6, 6-4, 6-4 victory.

Asked afterwards whether his antics were distracting for other players, Kyrgios lost his cool.

"What did I say to the umpire today?" he said.
