Novak Djokovic thinks the final showdown between Andy Murray at the ATP World Tour Finals for the right to end the year top of the rankings represents the biggest match between the duo.
Djokovic eased through his semi-final against Kei Nishikori 6-1 6-1, while Murray, on the other hand, struggled to a thrilling victory over Milos Raonic in his last-four outing earlier on Saturday that left him fatigued.
The prospect of the top two players in the men's game battling it out to finish 2016 as world number one is a special one - and the significance is not lost on Djokovic.
"I pretty much executed everything, tactically, that I planned to do," Djokovic said reflecting on beating Nishikori. "I had to start well and I did so obviously that helps, when you're playing a top player, to build the confidence.
"Kei was obviously a bit tired and was not close to his best tennis, but congratulations to him on a great season, and a great tournament and I hope to see him next season.
"It's been going in the right direction now on the court, it's getting better and now it comes to the last match of the year that everybody wanted and anticipated, so it will be a great final.
"Let's try to enjoy the occasion, and respect the great match that we are playing - because it's never happened before.
"It's going to be great to be a part of history with Andy. We have known each other for many years, and this is probably the biggest match we have played against each other, so let's enjoy it."
