Rafael Nadal has to wait for another year before he can give the WTF title another shot. That is the only major title missing from his CV after playing as a professional player for 13 years.
Despite the loss, Djokovic who captured the year-end title for a third time said that the no.1 rank in Nadal's hands is well deserved because the Spaniard has won 2 Grand Slam titles this year, the best out of all players this year.
Djokovic, a favourite to win this tournament, brought the curtain down on the 2013 season with a convincing 6-3 6-4 win.
Djokovic caught up with One Direction member Niall Horan after winning the championship.
It will be exciting to see how these two players perform in 2014 especially at the Australian Open where Nadal was missing earlier this year.
Meanwhile, Fernando Verdasco and David Marrero upset favourite duo Bob and Mike Bryan 7-5 6-7(3) 10-7 in the doubles final.
