Novak Djokovic's form is ominous as the Australian Open champion prepares to face Milos Raonic in the quarter-finals on Tuesday.

After a wobble in the opening round, second seed Djokovic has dominated his last three opponents en route to an 11th quarter-final appearance at Melbourne Park.

Eyeing a record-extending eighth Australian Open title, Djokovic once again looms as the player to beat in Melbourne.

We take a closer look at Djokovic as the 16-time grand slam champion prepares to meet 32nd seed Raonic on Rod Laver Arena.

Form and results

Stop Djokovic if you can. The world number two swept aside 14th seed Diego Schwartzman on Sunday. While the Argentinian proved a tougher test than Tatsuma Ito and Yoshihito Nishioka, Djokovic was far superior in the Melbourne sun. Hitting 38 winners and 31 unforced errors, the Serbian star closed out proceedings in just over two hours.

R1: bt Struff 7-6 (7-5) 6-2 2-6 6-1
R2: bt Ito 6-1 6-4 6-2
R3: bt Nishioka 6-3 6-2 6-2
R4: bt Schwartzman 6-3 6-4 6-4

Next up

Former world number three Raonic stands in the way of Djokovic and another trip to the semi-finals - a repeat of the 2015 quarter-final clash in Melbourne. Raonic blitzed Marin Cilic in straight sets to advance on Sunday. However, the Canadian's 0-9 record against Djokovic is a concern.

Draw

It is the match everyone is dreaming of. Djokovic against 20-time slam winner Roger Federer in the semis. That mouthwatering showdown could happen if Djokovic maintains his perfect record against Raonic and Federer gets past Tennys Sandgren.

What he said

"It obviously helps when you have a success on a global level. Of course, it has a very positive impact in your country. Serbia didn't really have a successful or long tennis tradition, before [Slobodan] Zivojinovic and Monica Seles. That was probably the first generation of successful tennis players coming from our country."
