On top of the world: Notable No 1s

Novak Djokovic on Monday set a record in men's and women's tennis for total weeks spent on top of the world rankings.

The 35-year-old winner of 22 Grand Slam titles is enjoying his 378th week in pole position, edging ahead of Steffi Graf who was on top of the women's rankings for 377 weeks in her career.

"It's surreal in a way to be that many weeks world No 1, to match Steffi Graf, who is one of the all-time greats of our sport, both men and women," said Djokovic, whose first spell at the top began in July 2011 after his maiden Wimbledon triumph.
