Djokovic centre of attention as he bids to win a historic 21st Grand Slam title

Serbian top seed Novak Djokovic will be the centre of attention as he bids to win a historic 21st Grand Slam men's title at a US Open lacking a slew of his fellow big-name stars.

Serena Williams, Roger Federer and Rafael Nadal are all missing the New York event through injury - the first major without the three of them in a singles draw since 1997.

Djokovic will be the main focus as he attempts to complete a rare calendar sweep of the Grand Slams and pull clear of Federer and Nadal in terms of major victories.

Australia's world number one Ashleigh Barty is widely considered as the player to beat in the women's singles, although Japan's defending champion Naomi Osaka is aiming to lift the title for the third time in four years.
