Five top contenders for the men's title at the Australian Open, which starts on Monday:

Novak Djokovic said he felt "emotional" following a warm reception from fans upon his return to Melbourne Park for a practice match against Nick Kyrgios on Friday.

Rafa Nadal will head into the Australian Open undercooked and with only one win to his name since September's U.S. Open, but it would surprise nobody if he retained the title he won for the second time last year.

 Nick Kyrgios took a cheeky dig at his critics after tickets for Friday's practice match with Serb Novak Djokovic sold out in 58 minutes, proving the Australian's huge box office draw.

Novak Djokovic dug deep to save a match point on the way to a 6-7(8) 7-6(3) 6-4 victory over Sebastian Korda in the Adelaide International 1 final on Sunday ahead of this month's Australian Open.
