In the men's tennis world, I don't know whether it is because of their own strength, or because the "big three" are too strong, so far, there has not been a player who may become a legend in the tennis world after the 90s.

I think that even if there are two or three Murray-level players after the 90s, Roger Federer, Rafael Nadal and Novak Djokovic's "Big Three" will not play for so long. Because if there were two or three Murray-level players among the post-90s players, it would be difficult for the big three at the end of their careers to reach the Grand Slam finals, and they would not stay on the field for so long! When a group of post-80s players rushed to seize power, the two post-70s kings, Pete Sampras and Andre Agassi, were less competitive, and the two could only choose to retire.
In the inheritance of the men's tennis world, the post-80s have perfectly completed the seamless docking with the post-70s. As Sampras and Agassi drew to an end, the post-80s wave came, with Marat Safin (born January 27, 1980), Leiden Hewitt (born February 24, 1981), Andy Roddick (born August 30, 1982), Juan Carlos Ferrero (born February 12, 1980), Roger Federer (born August 8, 1981) and others on the beach. Ten-year-old Rafael Nadal photographed Gustavo Kurten, the king of the post-70s clay, on the beach.
When Sampras retired with a record of 14 Grand Slam trophies and the men's tennis ranking of the world's first 286 weeks, he must not have imagined that the 80s would soon leave his record behind.
Safin was the first post-80s player to win a Grand Slam men's singles title and the first POST-80s player to rank first in the world in ATP men's singles. In 2000, Safin won the US Open. In the same year, at the age of 20 and 8 months, he became the world number one in men's singles. Sadly, Safine's career was short due to injury, and there were few seasons to stay healthy, with the 2005 Australian Open title becoming his last Grand Slam title.
In 2001, at the age of 20, Hewitt defeated Sampras to win the US Open, and after the game he became the youngest world Number One in ATP history at 20 years and 8 months. The 2002 Wimbledon title became his last Grand Slam title. It's hard to imagine that Hewitt started so high, but in the end, because of the post-80s talented players, he did not win a Grand Slam championship in the later stage.
On 3 November 2003, Roddick became the world number one in men's singles. At the 2003 US Open, Roddick won the only Grand Slam title of his career. Like Hewitt, because of the post-80s talent players, Roddick also missed the Grand Slam title in the later period.
Ferrero is the clay prince between Kurten and Nadal. In 2003, Ferrero won the French Open. In other Grand Slam tournaments, Ferrero has also reached the final four.
In 2003, Federer won his first Grand Slam title. In 2004, Federer became the world number one and remained there until 2008. During this time, Federer showed amazing dominance in men's tennis.
In addition to the above players born in the early 1980s, David Nalbandian, born on January 1, 1982, also had a good performance in the Grand Slam arena, reaching the final four in the Australian Open, French Open, Wimbledon and US Open.
After Federer rode the tennis crowd at the beginning of the 1980s, there was also a group of good players after the 1985s, such as Rafael Nadal born on June 3, 1986, Novak Djokovic born on May 22, 1987, Andy Murray born on May 15, 1987, Stanislas Wawrinka born on March 28, 1985, Juan Martin del Potro born on September 23, 1988, and Marin Murray born on September 28, 1988. Cilic and so on.
Federer, Nadal, Djokovic 's " Big Three" record is shocking, do not need to write more, everyone knows, here to write about, in the cracks to find the opportunity to survive other players.
Murray entered the top four of the ATP men's singles world ranking very early, because the dominance of the Big Three is too strong, Murray only won 3 Grand Slam titles, and only stayed in the ATP men's singles world number one position for 41 weeks, staying in the second, third and fourth positions for a long time. At Murray's peak, he had the privilege of being called the "Big Four" alongside Federer, Nadal, and Djokovic. Federer, Nadal, Djokovic and Murray have experienced major injuries in their careers, Federer, Nadal and Djokovic have all recovered and are still competitive in the Grand Slam arena, while Murray has not recovered well.
On the eve of his 21st birthday, Del Potro beat Federer to win the title at the 2009 US Open. He won a Grand Slam at such a young age, but he has only won one Grand Slam championship so far in his career, which shows how fierce the competition between the post-80s is.
Cilic won the 2014 U.S. Open men's singles title at the age of 26, which is relatively late among the post-80s Grand Slam winners.
Wawrinka won the Grand Slam title for the first time at the age of 28 (2014 Australian Open) at the age of 28 and 10 months, and there was a feeling of late success. Wawrinka won a total of 3 Grand Slam titles like Murray, tied for fourth among the post-80s men's tennis players.
Since the ATP had an official singles world ranking in the 70s, a total of 26 players have reached the top, including Nastasser and Newcombe after 40, Connors, Bjør Borg, John McEnroe after 50, Ivan Lendl, Wieland, Edberg, Becker, Thomas Muster, Thomas Muster after 70, Marcelo Rios, Moya, Kafernikov, Patrick Laft, Kurten, and Safin, Hewitt, Ferrero, Rodico after 80s Federer, Nadal, Djokovic, Murray, post-90s players have not yet reached the top of the ATP singles world rankings. In terms of numbers, the post-70s and post-80s are equally divided, and 8 people have reached the top. From the perspective of time, the post-80s are far ahead, the post-70s occupy the first place in the ATP singles world ranking for a total of 503 weeks, and the post-80s have now exceeded 1,000 weeks (this number has not yet been fixed).
In the Grand Slam arena, the post-80s players won 18 Australian Open men's singles titles, 19 French Open men's singles titles, 18 Wimbledon men's singles titles, 19 US Open men's singles titles, and a total of 74 Grand Slam men's singles titles. The post-90s players still have only one Grand Slam men's singles title (Dominic Tim, born on September 3, 1993, won the 2020 US Open men's singles title).
From the current situation, the tennis men's singles players after 90 will not appear in the historical level of players, the current age of the "big three" is already very large, according to common sense their speed, physical fitness and reaction ability should not be as good as the post-90s players, why the post-90s players in the Grand Slam men's singles field is still difficult to step over the "big three". Like this year's French Open signing table is very favorable to the post-90s players, Djokovic and Nadal are divided into the same half of the zone, but the post-90s players still can't seize the opportunity. In the future, when the "Big Three" comes to an end, the post-00s will shoot the post-90s on the beach, leaving little time and opportunity for the post-90s, and the fans have left hope for the post-00s.
Do you think that the results of the tennis men's singles post-90s players are because their own strength is not strong, or the strength of the "Big Three" is too strong to lead to poor results in the Grand Slam field, or both factors?
