2. Rafael Nadal
A lot remains unpredictable when it comes to the World No. 1 Rafael Nadal. With recurrent knee and wrist injuries, only time can tell whether the Spaniard can maintain his hold over the top spot.
He was far from his best on hard courts this year even though he did win in New York, where perhaps the depleted draw worked as a catalyst. But whatever happens on the quicker courts, Nadal's supremacy on red dirt means that he should have very little trouble staying inside the top five.
