As for whether Djokovic can win another Grand Slam in the new season, the answer is yes. The reasons are as follows: First, the Serbian state has shown a cliff-like decline in the past year and a half. It is not that there are too many problems in his technical and tactical system, but that the elbow injury has seriously affected his play.
For tennis players, elbow injury is very sensitive. It may not be so serious that you can't play at all, but it may limit your play in all aspects. Dejun has been fighting injuries since winning the 20 16 French Open. Now he has made up his mind to sacrifice half a season for the recovery from injury. I believe that his technical level will return to the peak soon.
Secondly, Dede has just turned 30 this year, which is actually the golden age of modern tennis players. After Germany's comeback, Federer and Nadal, his main rivals in the Grand Slam, were older than him. Although Fener won four Grand Slam titles in the 20 17 season, their physical factors are very uncertain. For example, Federer's level during this year's US Open was greatly influenced by physical factors. Morality is comprehensive in technology and stable in psychological quality. Once he recovers, it is not difficult for him to win a grand slam. Maybe he needs some time to find his feelings in the Australian Open and French Open in the first half of the year, but he may become a hot spot in Wimbledon and the US Open in the second half of the year.
