World No. 1 Novak Djokovic defeated Spaniard Rafael Nadal on Monday, a thrilling five-set victory, in what was described as the greatest Grand Slam singles final of all time at the Australian Open in Melbourne.

The 24-year-old Djokovic, out of sheer bliss, ripped off his sweat-soaked shirt and let out a scream on winning the Australian Open title with a final score is 5-7, 6-4, 6-2, 6-7(5), 7-5.

Jelena Ristic, Djokovic's girlfriend, also celebrated his victory as she cheered from the stands.

Djokovic and Nadal played a gripping match in front of an enthralled crowd early Sunday, in what was perhaps the longest title match in grand slam at 5 hours, 53 minutes.

A dejected Nadal was seen holding his head as the Serbian top seed took claim of the grand title for the third time in a row.

Djokovic becomes the fifth man to win three straight slams, joining the ranks of Rod Laver, Pete Sampras and Roger Federer. Opponent Nadal had also previously won three consecutive grand slams in the open era.

Following his win, Djokovic will go for the Nole Slam at Roland Garros in May.
