It's been a good year for Andy Murray to say the least. Having won his second Wimbledon title in June, he followed up with a second Olympic gold later in the summer before finishing off with the ATP tour title.
And in amongst this, he saw himself climb to number one in the world rankings for the first time in his career, something that will stand until the end of the year.
His place at the top of the pile did come under threat by rival Novak Djokovic, but Murray saw off the competition with an emphatic 6-3 6-4 victory at the O2 Arena in London.
This also extends the Scotsman's winning streak to 24 matches, as well as ending Djokovic's four-year run of success at the tournament.
Murray and Djokovic have contested 34 matches between themselves, and this win brings Murray up to 10 wins from 34.
"We've played Grand Slam finals and Olympic finals before, but I am very happy to win," he told the BBC.
"It is something I never expected."
A total of 17,000 fans flocked to the O2 to see the 29-year-old play, and after the meeting Djokovic paid his tributes to his counterpart.
"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."
And fans shared their delight at his success on social media, highlighting what a great year it's been for him.
