Shanghai: Novak Djokovic said on Tuesday he is relaxed about the possibility of Rafael Nadal opening up a huge lead at the top of the world rankings and that he believes he can repeat his astonishing feats of 2011.
Nadal this week replaced the Serb as world number one after collecting 10 titles this year and has the opportunity to widen the gulf as he has no points to defend for the rest of 2013.
"He deserves to be number one," said Djokovic, who beat his fierce rival in Sunday's China Open final in Beijing. "Results are there for him. Definitely he's so far the most successful player in this year.
