New Australian Open champion Novak Djokovic said on Monday he hopes to return to action in a month's time but is "not sure" how quickly his injured hamstring will heal.

The Serb also revealed that he had not had time to properly celebrate winning a record-extending 10th Melbourne title on Sunday.

"I'm not sure, I'm going to do some medical check-ups in the next few days," he replied. "Then I'll be able to talk about it a bit more and understand the situation."
