In an exclusive interview to Tennis World USA the Stuttgart Mercedes Cup chief Edwin Weindorfer commented on how the future of men's tennis will be once Roger Federer, Rafael Nadal and Novak Djokovic retired from the professional tour.
"Remember the last time we asked that question was after the Pete Sampras and Andre Agassi generation. We said, What's going to happen after them, then we had Djokovic, Federer and Nadal. There will be a future after them even if the last ten years have been the most dominating time in the Grand Slams with the Big Four only winning with the only exception of Stan Wawrinka and Marin Cilic.
It's tough to imagine but I think there will be great players and great careers." Rafael Nadal is instead unlikely to play in Stuttgart: "I think he did not enter in Queen's, but I do not know if he takes a wild card or not.
I do not know what his plans are. In the past two years, he was practising in the WTA tournament of Mallorca. With Rafa, the situation is very clear in Stuttgart. As long as he has chances to win the French Open, he will not enter in Stuttgart, but my priority is not Rafa.
It's Federer and Zverev." On Tommy Haas saying back in 2014 that coaching Federer would be his dream, Weindorfer added: "I never heard about that so it's interesting. I did not know. But Federer and Haas are very close friends, they see and meet each other a lot, especially in Indian Wells where Tommy Haas is the Tournament Director.
Roger's family and Tommy's family are very close. I am sure Tommy would agree to become Federer's coach."
