Rafael Nadal has become the most successful man in tennis history by winning the Australian Open and his 21st Grand Slam title.

He took on Daniil Medvedev in a gruelling five-hour and 24-minute marathon to clinch the trophy.

Most of the build-up focused on the historic significance of the Spaniard bidding for his 21st Grand Slam but he found himself under pressure from the start.

He saved two break points in a long third game but was then broken to love in the fifth as Medvedev, who was booed onto court by a section of the crowd, proved the steadier from the baseline.

Successive double faults then contributed to a second straight break and Medvedev served out the set 6-2.
