Novak Djokovic and Naomi Osaka walked away with the trophies after two compelling weeks of action at Melbourne Park.

Both made history, with Djokovic becoming the first man to win seven titles at the Australian Open and Osaka adding to her success by becoming the first Asian to be ranked world number one in singles.

Here, Press Association Sport picks out five things we learned from the tournament.

Djokovic can win the lot

With the asterisk that he was not playing Rafael Nadal at his fittest or best, Djokovic's final performance was simply tennis on another level. His remarkable physical abilities, combined with his efficient strokes and ability to guide the ball into the corners add up to the perfect package on a hard court. His apparently insatiable desire for titles means it seems less a question of 'Can he win the calendar Grand Slam?' but rather 'Who can stop him?'

Osaka can win a lot

With the emergence of a genuine, reliable superstar in unassuming 21-year-old Osaka, women's tennis finds itself in a very healthy place indeed. After blowing away opponents at the US Open, Osaka showed here that she can find a way to come through tricky matches and regroup when times get tough. It would be a surprise if she proved as effective on clay, but expect her to be a challenger at Wimbledon.

Murray might not be finished yet

Late finishes are nothing new but the sport must look at its scheduling and decide whether the current arrangement is really sensible. Johanna Konta and Garbine Muguruza did not begin their second-round match until 12.30am and finished after 3am in front of a handful of spectators. There is no need to play tennis in the middle of the night. As Muguruza said: "I seriously can't believe that there are people watching us at 3.15. I mean, who cares?"
