Novak Djokovic would not let Daniil Medvedev spoil his date with history a second time as he battled past the Russian 6-3 7-6(5) 6-3 to win the U.S. Open and equal Margaret Court's record haul of 24 Grand Slams.

Djokovic's victory, his fourth in 10 Flushing Meadows finals, capped another remarkable season after his wins at the Australian Open and Roland Garros, and he will return to the top of the world rankings when they are updated later on.

No man has won a calendar Grand Slam in 54 years, though Djokovic came close once again, losing in five sets to Carlos Alcaraz in the Wimbledon final.

But for the moment he is savouring his 24th Slam.

"It obviously means the world to me," he said. "I'm really living my childhood dream.

"To make the history of this sport is something truly remarkable, it's hard to describe the words.

"I had the childhood dream when I was seven, eight, I wanted to become the best player in the world."

As he continues to live his dream Djokovic is also staking his claim to the mantle of greatest tennis player of all time.

At 36 Djokovic also becomes the oldest U.S. Open men’s winner in the Open Era but the Serb's Grand Slam hunger has not dimmed and he had some bad news for his younger rivals.

"Eventually one day I will leave tennis in about 23, 24 years," he joked. "Until then, I guess you'll see me a bit more.

"I don't put any number right now in my mind on how many Slams I want to win.

"I'll continue to prioritize them as my most important tournaments and where I want to play the best tennis."
