Daniil Medvedev's brutal confession about wife in US Open speech

Daniil Medvedev may not have had the crowd on his side during Sunday's US Open final, but he certainly won them over with his funny and humble victory speech.

The Russian World No.1 shocked Novak Djokovic and the tennis world on Sunday, winning his first major with a straight-sets victory over the 20-time grand slam champion.

'NEVER SEEN THIS': Novak Djokovic in shock mid-match breakdown

Djokovic's bid for the first calendar-year grand slam in men's tennis since 1969 ended one victory short, with Medvedev prevailing 6-4, 6-4, 6-4.

The surprisingly lopsided triumph secured Medvedev his first major championship and prevented Djokovic from winning what would have been a record-setting 21st of his career.

Medvedev was loudly booed while serving for the match on multiple occasions, with the US Open crowd desperate to see Djokovic show some fight.

However the Russian won over the crowd that booed him in his victory speech.

The 25-year-old paid a classy tribute to Djokovic, thanked the crowd for their support and heaped praise on his team.

However he saved the best for last when he admitted he hadn't bought his wife a present for their third wedding anniversary.

"It's the third anniversary for me and my wife today," he said, sparking cheers from the crowd.

"During the tournament I couldn't think of a present so when I made it to the semi-finals I thought 'if I lose I'll need to find a present fast'.

"Then when I won the only thing I thought was 'well, if I lose (the final) I'll have no time to buy a present so I have to win this match'.

"I love you Dasha and thanks a lot."

Perhaps the $2.5 million winner's cheque will suffice for an anniversary gift?

The funny and sweet moment sent social media into a frenzy.

Novak Djokovic misses chance at tennis immortality

Djokovic entered this match 27-0 in 2021 at the sport's four most important tournaments, enduring the burdens of expectations and pressure that came along with his two-track pursuit of history over the past seven months and, in New York, the past two weeks.

He beat Medvedev in the Australian Open final on a hard court in February, then added titles on clay at the French Open in June and Wimbledon on grass in July.

But the 34-year-old from Serbia couldn't get to 28-0. He simply was far from his best on this particular day.

He made mistakes, 38 unforced errors in all.

Djokovic wasn't able to convert a break chance until it was too little, too late.

He showed frustration, too, destroying his racquet by pounding it three times against the court after one point, drawing boos from the Arthur Ashe Stadium crowd and a code violation from the chair umpire.

A lot of Djokovic's issues had to do with world No.2 Medvedev, who used his 1.98cm metre frame to chase down everything and respond with seemingly effortless groundstrokes - much the way Djokovic wears down foes - and delivered pin-point serving.

Djokovic reached his record-equalling 31st grand slam final with six victories on the hard courts of Flushing Meadows. But he could not quite get the last one he needed.

He remains tied with Roger Federer and Rafael Nadal with 20 major titles.
