Djokovic keeps his future vague: "I can't say if I'll play any more matches."

Novak Djokovic is no longer 20.

Closer to the end than the beginning, the Serbian chooses his tournaments in order to reach his peak form when he needs it, as his gold medal at the Olympic Games clearly demonstrated.

Taking part in Serbia's easy Davis Cup play-off victory over Greece, the Serb was asked about the rest of his season.

And while his presence at the Shanghai Masters 1000 seems assured, the rest of his schedule remains rather opaque: "Turin is not my objective at all, to be honest.

I'm not after the ATP Finals, I'm not after the rankings.

As far as I'm concerned, I'm done with that for my career (smile).

I can't say at the moment whether I'll be playing any more matches this year or in the future."
