Andy Murray beats Novak Djokovic to end 2016 as world number one

This was the first time the number one ranking had been decided on the final match of the season.

Andy Murray stood proudly on top of the tennis world after beating Novak Djokovic to win the ATP World Tour Finals and clinch the year-end world number one ranking.

It has undoubtedly been the finest season of Murray's career but it would have had a bitter ending had he not walked away with the trophy at London's O2 Arena.
