Record 21st for Nadal

Rafael Nadal roared back from two sets down to win a titanic five-set duel with Daniil Medvedev and claim a record 21st Grand Slam men's title in the Australian Open final on Sunday.

The Spanish great looked dead and buried as the Russian world number two carved out a two-set lead but Nadal surged home for one of his mightiest comeback wins 2-6, 6-7 (5/7), 6-4, 6-4, 6-4 in 5hr 24min on Rod Laver Arena.

Nadal came out on top in the physical war of attrition to move ahead of era rivals Novak Djokovic and Roger Federer on the all-time list of men's major winners.

Djokovic missed his chance to improve on his nine Australian Open wins when he was deported over vaccination issues on the eve of the tournament, while Federer is injured.

It was one of the 35-year-old Spanish warrior's greatest title victories in his 29th Grand Slam final winning his second Australian Open, 13 years after his first in 2009.

Nadal also became only the fourth man to win each of the four Grand Slams twice and the third oldest man in the Open Era to win a Grand Slam title, behind Ken Rosewall and Federer.
