Andy Murray has vowed to give everything he has left against Novak Djokovic in the final of the ATP World Tour Finals.

The top two players in the world will face each other on Sunday with the number one ranking up for grabs.

Murray made the final with an epic three-set win over Milos Raonic, breaking the record for the longest match every played at the competition. Djokovic, on the other hand, breezed past Kei Nishikori 6-1, 6-1.

The Scot entered recovery mode as soon as he came off the court at the O2 on Saturday, spending 10 minutes in the ice bath before a session of stretching and massage.

He said: "I don't know how I'll feel tomorrow. Obviously I'm tired just now because it was a really hard match. It wasn't just that it was physically hard, it was mentally a tough match, too. It was pretty stressful.

"I was quite far behind obviously in the second set. A set and a break down, I managed to turn it round. Then it was back and forth in the third set.

"Obviously tomorrow is the last day for a while, I get a break after that. I'll just give my best of what I've got. Hopefully it's enough."
