Novak Djokovic put the cherry on top of a superb season with a victory at the ATP World Tour Finals in London on Sunday.
The world number one avenged his earlier loss to Roger Federer when he defeated the Swiss maestro 6-3, 6-4 on the hard courts of the O2 Arena.
It was a match that yielded few opportunities for Federer, with Djokovic saving the only two break points that the world number three earned.
Both players defended a break point before the Serb broke first to take a 3-1 lead in the opening set.
Djokovic would then save the only other break point Federer would engineer during the final in the sixth game. The top seed then sealed the set in style with another break.
In the second set, the duo traded service games, neither giving man giving an inch. Djokovic appeared to have Federer on the ropes at 0-40 down and four games apiece, but Federer rallied to save all three break points.
But two games later Djokovic would have two match points in hand and despite Federer challenging the line judge, his shot was indeed long, cueing celebrations from Djokovic and his camp.
Federer's aggressive style of play lead to him edging Djokovic 19-13 on winners, but ultimately, Djokovic's excellent defence forced Federer to notch up 31 unforced errors, costing him the match.
The win sees Djokovic earn his fourth consecutive season-ending ATP World Tour Finals title to cap off arguably the best ATP season on record, with an 82-6 win/loss record and 11 titles, including three grand slams.
