Australian Open: Men's singles fact pack

- In claiming his fifth men's singles crown at Melbourne Park in 2015, following previous wins in 2008, 2011, 2012 and 2013, Djokovic set a new record in the Open Era. He will now aim to equal the six wins achieved by Roy Emerson as an amateur.

- Djokovic participated in the longest grand slam final in 2012 when he beat Rafael Nadal in a match lasting five hours and 53 minutes to secure a third Australian Open.

- Last year's Australian Open was the first since 2003 in which neither Roger Federer nor Nadal managed to reach the semi-finals.

- Federer needs three more wins to reach 300 grand slam victories in his career, while Nadal requires two to hit 200.

- Federer has lost only two games against an unseeded opponent at the Australian Open in his career: vs Arnaud Clement (2000) and Andreas Seppi last year.

- Djokovic dropped only three sets in the 2015 Australian Open - two in his semi-final triumph over Stan Wawrinka and one in the final against Andy Murray.

- Nadal could secure his 15th grand slam title and overtake Pete Sampras, while Djokovic is looking to level Bjorn Borg with 11.

- Andy Murray has been runner-up at the Australian Open four times so far (incl. last year) – only John Bromwich has lost more finals than him in Australia (five between 1937 and 1949).

- The 2006 Australian Open was the last in which there was no Spanish representation in the quarter-finals.
