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 No 2 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 the 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 is eager to stress beating Djokovic is not in any way an obsession. "I'm not working every day thinking about Novak, I'm working every day thinking what I need to do to be a better player, and that's what I need to keep doing," Nadal said.
