Novak Djokovic overpowered Roger Federer 7-6 (8-6) 7-5 to win his first ATP World Title in London. Held in the spectacular 02 arena, world no.1 prevailed after 2 hours and 14 minutes to win his second season-ending title since he won in Shanghai four years ago.

He dedicated the win to his father, who has been struggling with a serious illness.

"Throughout the whole season I've had lots of success and had some disappointing losses at big events, in a couple major finals. But, you know, all in all, it was a fantastic year, you know, where I've had to face a lot of difficulties off the court as well. And you know, especially coming into this tournament, having my father fighting his own fight, you know, for health gave me extra strength that, you know, I wanted to play for him in a way and that's one of the reasons I really gave it all every match, especially tonight. This was a title for him."

Federer was aiming to win a record seventh-season ending title, and admitted that on the night he couldn't find a way past the world no.1.

"Maybe a bit of regret because I had the lead twice first before him but at the end of the day that doesn't matter. You have to get over the finish line in the set and then obviously at the match. He was better at that today. You know, I thought it was a good match. It was great intensity and good crowd so it was fun playing."

The win caps another remarkable year for Djokovic at the top of the sport, but he has hardly been dominant. 2012 saw four different champions at each of the slams, as Nadal, Federer and Murray all won major titles along with the Serbian. Djokovic hasn't won a slam since the Australian Open back in January, which he will looking to defend when the season starts again in the new year.
