For all the talk of the current "Golden Era" of tennis, Boris Becker says there's only one Golden Boy who could have competed alongside his generation of greats: Roger Federer.

"I don't think [Rafael] Nadal or [Novak] Djokovic would have been so successful in the era of serve and volley, but Federer could have played," Becker said at the Hindustan Times Leadership Summit in New Delhi over the weekend.

He added that Federer's variety puts him ahead of Nadal and Djokovic.

"The reason why Federer is still successful at the age of 31 is because he has got a good technique," Becker said. "He can play from the baseline and when he has to, he can also come to the net more often than other players."

As for whether Federer is the best player of all time, Boris was more inclined to hedge.
