"His son was born in October and right after he had to play tournaments, and we know the results, it was good for his spirits," Becker was quoted as saying by the Herald Sun.

“It’s a natural progression to settle down and have a family and, if anything, it prolongs a tennis career. Because you are a human being, man or woman, and you do have a private life and once that’s settled it helps your career.”

On his association with the Serb, Becker said: "It’s wonderful when you work with a player and the only aim is to win."

Becker became Djokovic's training staff head coach Dec 18, 2013. The Serb has seven Grand Slam singles titles to his credit.
