Novak Djokovic has insisted that he will take positives from his shock defeat to Sam Querrey in the second round of the Paris Masters.
The Serbian, who is guaranteed to end the year at the top of the rankings, was beaten 6-0 6-7 4-6 by the American world number 22.
"It's unfortunate, but on the brighter side, I have a little bit more time to rest because I had really difficult period in the last couple of weeks," said Djokovic.
The five-time Grand Slam champion will now turn his attention to the ATP World Tour Finals which start on Monday in London.
