Despite the win, his second of the week in the end-of-season tournament, Djokovic is still not certain of making it through to the semi-finals.
But while a victory for Jo-Wilfried Tsonga over Tomas Berdych on Wednesday night would see him qualify, the Serbian will not be watching. He instead has bigger plans for his evening - walking his poodle, Pierre.
"I'll just enjoy this victory - I don't want to take part in calculations, I just play every match to win," he added. "I have to walk my dog tonight. That's my primary focus now."
Murray, meanwhile, is still in contention to finish in the top two in Group A - he finishes his round-robin campaign against Tsonga on Friday.
