Nadal aims to end on high in Tour Finals

LONDON, Nov 19 (AFP): Rafael Nadal has vowed to finish a frustrating campaign on a high as the world's top players gather in London for the ATP Tour Finals. Although world number two Nadal claimed a sixth French Open crown this year, his campaign has been marred by Novak Djokovic's remarkable ability to defeat him time and again at thse final hurdle. The Spaniard lost six successive finals to Djokovic, including at Wimbledon and the US Open, and surrendered his spot on top of the world rankings to the Serb as a result. Nadal has been open about the psychological impact those defeats have had, but he is eager to stress beating Djokovic is not in any way an obsession. Nadal opted to take a month off after disappointing defeats against Andy Murray and Florian Mayer in Asia after the US Open, meaning he will head into the end of season showpiece in London short on match action but still with a positive mindset.
