Daddy Novak feels 'fulfilled'

Novak Djokovic says his life is "completely fulfilled" as he bids to become the first player since Roger Federer to win a Grand Slam title after fatherhood.

The Serb world No 1, gunning for his fifth Australian Open crown and eighth overall Slam in Melbourne, speaks glowingly of his new life as a husband and father.

Djokovic, 27, married longtime partner Jelena Ristic in July last year and the couple had their first child, Stefan, in October.
