Andy Murray beats Novak Djokovic to seal world number one spot

Andy Murray has gone 24 matches without defeat

Andy Murray beat five-time champion Novak Djokovic to win his first ATP World Tour Finals title and end 2016 as the world number one.

With the top ranking on the line, Murray won the final 6-3 6-4 at London's O2 Arena.

"I'm very happy to win and to be world number one is very special," said the Scot. "It's very special playing against Novak in a match like this."

Murray extended his winning run to 24 matches, the best run in his career.

"Andy is definitely number one in the world," said Djokovic. "He deserved to win. He is the best player."
