Coach Patrick Mouratoglou says he feels Novak Djokovic is the Big Three group member that has the best chance of playing at the highest level for a few more years. This past Sunday, 35-year-old Djokovic clinched his 21st Grand Slam title after beating Nick Kyrgios in the Wimbledon final.
Nadal, 36, is a record 22-time Grand Slam champion but he was forced to give Kyrgios a walkover in the Wimbledon semifinal because of an abdominal injury. Nadal is still a strong force in the game but he is often struggling with injuries.
On the other side, 40-year-old Federer hasn't played since last year's Wimbledon. Mouratoglou says it's awesome to see Federer returnign but doubts the Swiss can win a Grand Slam again.
Mouratoglou on Federer, Djokovic & Nadal
"Rafael Nadal is playing some of the best tennis of his life, recently beating Novak in the quarters of the French Open, but he still struggles a lot with his injuries," Mouratoglou said in a video posted on his Instagram.
"Novak is the youngest of the three and is in great physical condition. So he has a chance of playing at the highest level for a few more years, however, he might be unable to compete at the next two Slams - at the US Open and the Australian Open - means his next shot at a title may be in Rafa's house at the French Open next year.
Roger turns 41 soon and is planning to return to competition at the Laver Cup and the Swiss Indoors in Basel. It will be incredible to see him back on court but to see him win another Major is highly unlikely."
Nadal is a record 22-time Grand Slam champion, while Djokovic is now the second with 21 Grand Slams.
Federer, who hasn't won a Grand Slam since the 2018 Australian Open, is the third with 20 Grand Slams. Federer is expected to return to action in September but there is not a strong chance of seeing him at the US Open. Federer will likely make his comeback in late September at the US Open.
