Novak Djokovic has set his sights on following his successful defence of the ATP World Tour Finals by leading Serbia to glory in the Davis Cup final.
Djokovic won the prestigious season-ending Tour Finals for the third time with a dominant 6-3, 6-4 victory over world number one Rafael Nadal at the O2 Arena in London yesterday.
The 26-year-old has played some of the best tennis of his life since losing the US Open final against Nadal in September and Monday's win was his 22nd successive match victory -- a run that has brought him titles in Beijing, Shanghai, Paris and now London.
But, although Djokovic could be forgiven for wanting a well-earned holiday after such an intense period, the world number two has no time to rest on his laurels because he will now fly to home to Belgrade to prepare for the Davis Cup final clash against holders Czech Republic, which starts on Friday.
Serbia last won the Davis Cup in 2010 and Djokovic would dearly love to repeat that triumph.
"It's a fact that it's been a very long season for me and I'm exhausted in every way. But God knows if we're going to have as a country another opportunity like this to win a Davis Cup title at home," Djokovic said.
"We have very tough opponents, the defending champions, but the Davis Cup is the only team competition in our sport that brings the best possible energy and willpower in me.
"I'm going to do my best to recover the next three days and get ready for that one."
Once Djokovic has finished with his national service, he will finally be able to put his feet up and reflect on a year that brought him joy and despair in equal measure.
After winning the Australian Open for the fourth time in January, he suffered a frustrating semi-final loss to Nadal at the French Open -- the one Grand Slam title he has never won.
That was followed by a Wimbledon final defeat against Andy Murray and another painful loss at Nadal's hands in the US Open that eventually led to the Spaniard replacing Djokovic at the top of the world rankings.
