On 20 18128, Beijing time, in the men's singles final of the Australian Open in the 20 18 season, the defending champion Federer defeated Croatian player Siric 3-2 and lifted the Australian Open men's singles trophy for the sixth time, which is also the 20th Grand Slam champion in his career.

During Federer's four-and-a-half-year Grand Slam championship drought, many tennis experts were not optimistic about his prospect of winning another Grand Slam. At that time, many Federer fans posted such signatures on social media: Never change your name, never win 18, never shave ... This actually contains a lot of banter and self-mockery. However, Federer didn't keep the fans waiting. Last year's Australian Open, he had the last laugh when he was not optimistic. Soon, his number of Grand Slams at Wimbledon increased to 19, and now the number has exceeded 20.

It is meaningless to argue whether Federer has become the "best in history" now. His achievements and promotion of tennis have reached the pinnacle. Of course, in the rest of his career, he still has many records to break-

Federer's grand slam champion has ranked first among all male players, and there is already a gap of four with Nadal, who ranks second. In front of him, there are several women players who have won more Grand Slams, including Courtney with 24 champions, Serena with 23 champions and Graf with 22 champions. With Federer's competitiveness in this Australian Open, we can consider attacking these characters.

Federer has won the Australian Open men's singles championship six times, tied for the most with Djokovic and Emerson. Among them, Emerson's champion came from before the Open, and only Djokovic could compete with Federer for the title of "King of Melbourne".

Federer is nearly 37 years old, but he is not the oldest grand slam men's singles champion in the open era. Roswell celebrated her 37th birthday when she won the Australian Open men's singles title on 1972, and Federer is expected to surpass the famous woman's record next.

At present, Federer's best performance in four Grand Slam events is Wimbledon, and he has won the championship eight times so far. However, there is still a gap between Nadal's achievements in the French Open, which can also be the goal of Federer's next efforts.

Now let's not discuss what kind of achievements Federer has to achieve in order to completely secure the position of "the best in history", because no one knows where the limit of this great champion is.
