Nadal seems to have overcome his initial nerves and gets back on level pegging, it's 3 games all Photograph: Tom Jenkins

There's a cracking response from Djokovic to losing three games on the bounce, as he holds his serve to retake the lead 4-3. Then in the next game a spectacular rally ends with a fantastic dink over the net by Djokovic to break Nadal's serve, it's 5-3 Photograph: Tom Jenkins

Rafael Nadal needs to reign in the unforced errors if he's to stop Djokovic from running away with the match Photograph: Tom Jenkins

Initially it doesn't seem like he has as the Serb takes a 3-1 lead in the second set. The following service match by Nadal is a must-win game for the Spaniard, and he does with a forehand shot landing on the baseline. Both players then hold serve to make it 4-3 in the second, however, inspite of the scoreline, Djokovic is in total control of this second set Photograph: Tom Jenkins

Djokovic continues to dominate and takes the next game to make it 5-3, he's one game away from retaining his title Photograph: Tom Jenkins

Nadal takes the game with a free-wheeling forehand winner. However Djokovic remains one game away and he'll serve for the title Photograph: Tom Jenkins

He's done it, Djokovic takes the ATP World Final title for the third time Photograph: Tom Jenkins

Nadal understandably looks shell-shocked after his 6-3, 6-4 defeat. The Spaniard hardly hit any winners during the match in what was, a few games apart, a pretty one-sided match with Djokovic dominating the serve and rallies Photograph: Tom Jenkins

Confetti falls as the triumphant Djokovic starts his victory speech. That's 22 wins on the trot - he's undefeated after his US Open defeat to Nadal back in September, which must give him confidence as he heads into the Davis Cup Final with his Serbian team-mates Photograph: Tom Jenkins
