Novak Djokovic suffered an easy defeat to Roger Federer in the group stage of this year's ATP World Tour Finals, but that didn't happen again in the final. As he demonstrated throughout 2015, the Serbian player reaffirmed his status as the current number one with unstoppable power.

With swift and convincing play, Djokovic swept aside the Swiss legend in 80 minutes with scores of 6-3, 6-4. Djokovic thus leveled the head-to-head record with Roger at 22-22. Earlier in the semi-finals, Djokovic had also leveled the head-to-head record against another tennis legend, Rafael Nadal (23-23).

This is the fourth consecutive year that Djokovic has won the World Tour Finals, the tournament for the players with the best performance of the year. Djokovic is the first person in the tournament's 45-year history to achieve this feat four years in a row.

2015 was a hugely successful year for Nole, with the Serbian player breaking numerous records. He won three Grand Slams and reached the final of the third. Djokovic finished the year as the ATP No. 1, for the fourth time in the last five years.
