Veteran tennis star Roger Federer has fallen outside the world's top 10 for the first time since 2002.
While Andy Murray's rise to world number one was the main talking point of the new ATP rankings, 17-times major champion Federer's slide to 16th was largely overlooked.
The Swiss ended his season in July in a bid to recover fully from knee surgery, although he is aiming to be fit for the Australian Open in January.
Former great Stefan Edberg said Federer could still win another grand slam title.
At 35, however, logic suggests Federer's days of challenging for silverware may be numbered, with his last grand slam title coming from Wimbledon in 2012.
But former world number one Edberg, who has coached Federer, disagrees.
"It becomes even tougher, he is not young any more but there is still hope. If there's one who can do it, it's Roger," he said
