It is a sight that people who watched it will remember for a long time to come. In his 30th Grand Slam final, a tearful Roger Federer surged home to beat Marin Cilic in five riveting sets. He pumped his arms, both relief and disbelief showing on his face. Such was the emotion, he broke down in tears by the end of his victory speech.

This was his sixth Australian Open and 20th Major title – an feat made even more incredible by the fact he is 36, an age most tennis players have hung up their boots.

This was his third Slam in the last year, extending his own lead for a record 20 trophies. His overall his Grand Slam mark stands at 332-52. The Swiss also became the first man to join the 20 Grand Slam club, with his first coming back in 2003.
