Raonic match one of the hardest, claims tired Murray

Andy Murray has pledged to give the best of what he has left in the final of the ATP World Tour Finals as he aims to defeat Novak Djokovic and end 2016 as world number one.

The Scot overcame Milos Raonic 5-7 7-6 (7-5) 7-6 (11-9) in a thrilling semi-final at London's O2 Arena on Saturday, with a final against Djokovic for the honour of finishing the year top of the rankings. 

Murray's victory extends his winning streak to a career-best 23 matches, while the three hours and 48 minutes it took to defeat the Canadian set a new tournament record.

And the 29-year-old admitted that he is suffering from the fatigue ahead of Sunday's final.

"I didn't expect to play a long one with someone with a serve like Milos," Murray, who also praised the atmosphere at the O2 Arena, told BBC Sport.

"This is one of hardest matches I've played indoors.

"I'm tired. I've played so much tennis over the last few months. I'll give it my best effort - the best of what I have.

"It was an amazing atmosphere. The longer the match went on, the louder the crowd got.

"This is what we play for. Matches like this and arenas like this."
