Daniil Medvedev cut a dejected figure after his loss in the Australian Open final, blowing a two-set lead before falling to Rafa Nadal in a five-hour epic.

But the Russian's actions in the aftermath of the match didn't exactly do him any favours with the Australian Open crowd.

Medvedev looked like he wanted to be anywhere else but the post-match presentation and was caught on camera mouthing 'boring' while Tennis Australia chair Jayne Hrdlicka was speaking.

Hrdlicka congratulated Medvedev on his run to the final in Melbourne, but the World No.2 didn't seem to want a bar of it.

“Daniil, you have had the most extraordinary tournament. You have found yourself in tough spots on the way here," she said.

"You have demonstrated you’re never finished and you were never finished until the very last point. Congratulations on a great tournament.

“You were clearly determined to boot history in the making for the second time in a row and that didn’t happen tonight, but there is no doubt that we are going the see you back here and that you are on your way to making your own records in the tennis history books. Congratulations.”

Medvedev could be seen mouthing 'boring' while Hrdlicka was speaking, and did so again after she'd finished.

He also seemed perturbed when the crowd cheered his efforts after being booed by them for two weeks.

Daniil Medvedev's ugly battle with Australian Open fans

The enigmatic Russian conceded during the on-court presentation that he simply couldn't go the distance with Nadal, who surged to a record-setting 21st grand slam men's singles crown early on Monday morning.

"(The match) was insane. I think the level was very high," Medvedev said.

"You (Nadal) raised your level after two sets (to win) a 21st grand slam.

"I thought he was going to get tired and maybe he did just a little, but still won the match."

A snarling Medvedev continued his battle with local fans, having first drawn their ire when he said those who booed him during a second-round win over Nick Kyrgios "probably have a low IQ".

The 25-year-old repeatedly berated chair umpire John Blom for not silencing the crowd at crucial moments during Sunday night's final, urging him to "take control".

"Step up, man, it's the final of a grand slam!" Medvedev shouted at Blom after dropping serve to fall behind 3-2 in the fourth set.

"(Saying) 'please' is not enough. They are idiots. With idiots, 'please' doesn't work. Step up."

Medvedev, who struggled with leg cramps and looked increasingly weary as Nadal fought his way back into the match, gave the crowd sarcastic applause several times after they cheered his errors.

He then appeared to troll the crowd in his runner-up speech when he didn't thank them, instead thanking his team twice.

It seemed as though Medvedev was building towards thanking the crowd, saying “Last but not least”, before saying, “just wanted to thank my team again.”
