Great Britain's Andy Murray has finished the year as the world No.1 ranked male tennis player, following a straight sets win over Serbian Novak Djokovic in the final of the World Tour Finals on Sunday evening.

Murray defeated Djokovic, who has spent 122 weeks at No.1, 6-3, 6-4, to win his first World Tour Finals event.

He becomes the 17th man to hold the world No.1 ranking since the introduction of the ATP rankings in 1973.

“Right now to finish the year like this, this is the best possible way, obviously,” Murray said post match.

“It was just a huge match to try and finish number one. This is a major event and one I've not done well in in the past, so it's been a great week.

“It was a big, big match against someone that would be my main rival really throughout my career.

“We played in all of the Slam finals, Olympics, and now a match to finish the year number one. It was obviously a big match, a very important win for me.”
