21 and 20, although they are both 2 words, but the meaning is completely different, especially for the big three in the men's tennis world, when standing at the historic moment when they are about to win their 21st Grand Slam championship trophy, they can't stop their hearts.
Even if he is full of glory, he has fought countless battles in his lifetime.

In the 2019 Wimbledon final, Federer and Djokovic reached the decider. The greatest player in the history of the All England Grass Club holds 2 championship points in his own serve and his 21st Grand Slam title at his fingertips. But in the face of the great feat of 21 crowns, the Swiss king's heart was flooded, and none of the 2 championship points of the serve to win the match were cashed in, and Djokovic dragged the game into the grab seven, and wasted 1 championship point when stealing 8-7 of the seven, and finally lost in the long game 12-12 after the grab seven, and rubbed shoulders with his 21st Grand Slam championship trophy.
This is the greatest final in the history of Wimbledon, but it is an eternal pain in the heart of the Swiss king.
In the 2021 US Open final, Djokovic is preparing to achieve the grand slam of the year with the momentum of winning the Australian Open, French Open and Wimbledon championships, while impacting his 21st Grand Slam title trophy. However, in the face of the supreme glory of double honor, Djokovic's performance was astounding, and he was beaten by Medvedev without the ability to fight back, failing to achieve the annual Grand Slam achievement and missing the opportunity to win his 21st Grand Slam title.
Like the 2015 French Open final, this US Open final was the two most regrettable finals of the Serbian King.
Fast forward to the 2022 Australian Open, and Nadal has also given himself the opportunity to attack his 21st Grand Slam title. Objectively, Deyo's absence created a golden opportunity for Natto to unlock a double-lap Grand Slam, and the King of Clay especially cherished this opportunity, and despite a slight wave, Natto still reached the final.
Will what happened to The Cow and Djokovic when they hit the 21st crown also fall on Natto?

At this point, Natto is only one step away from repeating the mistakes of the cow and Djokovic.

In the third set, Natto saved 3 break points in the 6th set, struggling to save the serve, which also became a watershed moment in the final, after which the king of clay became more and more courageous, first completed the break in the 9th set, and then dropped 4 straight goals in the winning set to complete the save, pulling the set to 1-2.
In the fourth set, Natto's experience and will once again helped him win the game. Mei's total physical fitness began to decline, the number of mistakes increased, Natto took the lead in breaking, and finally dropped 4 straight goals in the serve win set to complete the save, dragging the game into the decider.
In the decisive set, the king of the clay that has returned to the blood is unstoppable, although Mei Zong made a tenacious counterattack, but in the face of natto, who is more and more courageous in the Vietnam War, Mei Zong's australian Open first crown is more and more difficult.
Although Natto finally had a wave in his heart in the 10th set, which was also his first serve to win the game, and was chased by May to a 5-5 score, Natto quickly adjusted his mentality, immediately completed the breakback, and won the game by 4 straight goals in the second serve win.
Throughout the game, the two sides fought for 5 and a half hours, and Natto won the most important Grand Slam championship trophy of his career and the most difficult one for himself with his tenacious will and physical strength.
