ATP World Tour Finals 2016: Battleground for two Murrays’ No1 hopes, plus more facts and figures
The season-finale of the ATP World Tour takes place at The O2 in London from Sunday, and here is everything you need to know

The O2 will be the battleground not only for the No1 ranking between old adversaries Andy Murray and Novak Djokovic, but also for Murray’s brother Jamie in the coming week.
The elder Murray has qualified for the World Tour Finals doubles competition for the second year in a row, but for the first time with current partner Bruno Soares. For theirs is a partnership that flourished immediately.
After two Grand Slam final finishes last year with John Peers, Murray struck gold with Soares in Australia and they won again at the US Open. Ahead of the clay season, the duo rose to No1 in the rankings, only for the burgeoning French pairing of 34-year-old Nicolas Mahut and 25-year-old Pierre-Hugues Herbert to supplant them. Now the two teams contest both the individual No1 ranking and the team No1 ranking.
The permutations are, as always in the round-robin format, many and complex, but Mahut at least knows that, if he wins just one match in London, he will be top of the individual doubles rankings—the first Frenchman to do so.
Mahut and Herbert are also favourites to top the doubles rankings, which would make them the first French team to finish at No1.
However, it is still possible for Murray and Soares to steal the team No1, and if both Jamie and Andy Murray triumph, it would be the first time that brothers have finished at No1 in singles and doubles in the same year.
But the scale of the younger Murray’s task in retaining the No1 singles spot is not insignificant: His round-robin opponents represent four Grand Slam titles and one runner-up between them, and their recent form is written all over their head-to-heads.
Murray is 9-7 against Stan Wawrinka, but won just one of their last four matches. He is 11-3 over Marin Cilic, though lost their last meeting in the Cincinnati final. Against Kei Nishikori, Murray is 7-2, but also lost his last meeting, a dramatic five-set quarter-final at the US Open.

Meanwhile, five-time champion Djokovic, is unbeaten in London since winning in 2012. The formidable Serb has two tournament debutants in his group, No6 Gael Monfils and No8 Dominic Thiem, along with Milos Raonic, whose form is uncertain after picking up a thigh injury at the Paris Masters. Against possible substitute David Goffin, Djokovic also has a flawless record.
If the defending champion wins at least two round-robin matches and goes on to win the title, he can reclaim the No1. If Murray wins the title, irrespective of how many round-robin matches he wins, he will stay at the top.
But Soares summed it up for all of them: “I think being No1 would come with a good result, and right now it doesn’t really depend on just us. So we have got to focus on our own thing.”
So what else is at stake during what Jamie Murray called “the biggest tournament we have on the ATP tour”?
