Rafael Nadal enters the season finale as the top ranked player and player of the year. He has enjoyed great success this season but has yet to win this event, which favors more aggressive players, on the fast indoor court. Novak Djokovic is the defending champion and looks to defend his title and reassert himself as the top player. He has the toughest group but is in great form and has the stamina to prevail. Roger Federer has endured a difficult season but recent strong performances show he cannot be counted out, though his group is unfavorable.
