Djokovic strikes back after fall in rankings

Shanghai Masters champion Novak Djokovic said he still has unfinished business this season after delivering the perfect response to being knocked off the men's top ranking.

The soon-to-be-married Serb ceded the world No 1 spot to Rafael Nadal, but his reaction has been emphatic with an unbeaten run in China adding two titles to his collection.

Immediately after Nadal returned to No 1 by reaching the China Open final, Djokovic proved he was not about to go away by defending his title from the Spaniard in straight sets.
