Andy Murray continued his fine form after beating longtime rival, Novak Djokovic to win the ATP World Tour Finals title, his first, and end the year at the top of the rankings.
The Tour Finals title was not the only thing on the line, with the top ranking on the line, the Brit won 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, 29, extended his career-best winning run to 24 matches.
Murray, who had won 10 of the pair’s previous 34 encounters, added: “We’ve played Grand Slam finals and in the Olympics before, but I am very happy to win.
“It is something I never expected,” he said, his win capping off a weekend that also saw brother Jamie Murray and partner Bruno Soares crowned world number one doubles pair.
“Andy is definitely number one in the world,” said Djokovic. “He deserved to win. He is the best player.
“In the decisive moments, I wasn’t able to come back. I played better late in the match but it wasn’t enough.”
