Melbourne - World No 1 Novak Djokovic has been singing the praises of fatherhood in Melbourne after the birth of his first child Stefan last year. His coach is Boris Becker whose biggest rival during his playing days was Stefan Edberg, now mentoring Roger Federer. But Djokovic denies his son is named after the Swedish great. "I have nothing to say about it. I didn't name my son after Stefan Edberg, if you refer to that," he said, before ending the conversation.
