Djokovic, who began the year by winning the Australian Open, came from behind in both sets to end Swiss Federer’s hopes of a seventh title at the year-ending tournament.
In a tight game that bellied the straight-sets margin of victory Djokovic won a total of 96 points in the match – just one more than the former world number one.
Federer started in blistering fashion but the 25-year-old Serb hit back from 3-0 down in the first set before take a thrilling tie break.
The match seemed certain to be heading to a deciding set with Federer leading 5-4 and with two set points for the second set.
However, Djokovic won four points in a row to break back and, after holding his own serve, he broke Federer again to claim victory after two hours 14 minutes of absorbing action.
