Five-time Australian Open champion Novak Djokovic on Sunday backed Andy Murray's plan to quit the tournament if his wife goes into labor, saying he would do the same thing.

World No 2 Murray has made it clear he will not hesitate to pull out and dash home to be with wife Kim Sears for the birth of their first child, even if it meant robbing the event of its men's final.

Djokovic, who is seeded to meet the Scot in the Jan 31 decider if all goes to schedule, said it was a very personal decision and one he supported.
