Roger Federer and Novak Djokovic have been the two best players in the season, and it is no surprise the two modern greats will battle it out for the prestigious ATP World Tour Finals title at the O2 Arena in London on Sunday.
Their rivalry has been one of the best in recent times, as they have produced some stupendous display on the tennis court. Federer is the only player during the season to have troubled Djokovic, who has a 4-3 head-to-head record against the Swiss ace in the calendar year.
However, Federer has already tasted success earlier in the week against Djokovic, who suffered a straight-set loss against him in the round-robin stages. Apart from this victory, Federer has also played some sublime tennis in the finals of the Cincinnati Open in August to defeat Djokovic in straight sets 7-6 and 6-3.
With such record under his belt, Federer, who has won six ATP World Tour Finals in his career, should be upbeat in the year-end finals. Djokovic, who on the other hand has dominated the ATP circuit for some time now, has won the last three editions of the year-ending competition.
Irrespective of the result of Sunday's final, Djokovic will be pleased with his overall performance in the season, which saw him win a number of titles including the Australian Open, Wimbledon and the US Open. If he manages to win the ATP World Tour final as well, it will prove to be the icing on the cake and continue his dominance in the men's circuit.
"Regardless of the outcome of tomorrow's (Sunday) match, the season will still be the best I had," ESPN quoted Djokovic as saying.
"There is always room for improvement, so that's something that honestly excites me and motivates me to keep on going. I've had a terrific career and I'm very proud obviously with my team to be able to achieve what I have achieved in the last 10 years of professional tennis.
"But I still feel like I want to do more, and I can do more."
Djokovic comes into this final with a thumping win against Rafael Nadal in straight sets, with the score reading 6-3 6-3.
Federer is aware the year-ending finals will be a difficult match for him, but promises to come up with his A-game.
"He's had a tremendous year, another great semifinal against Rafa [Nadal]. I know it will be difficult tomorrow. I'll give it all I have, it's the last match of the season," said Federer.
With such quality players in the offing, the final is expected to be a humdinger of a contest. Irrespective of the winner, the expected jam-packed crowd at the O2 Arena will be treated to a mega spectacle on Sunday.
