Andy Murray has vowed to remain focused on his final ATP World Tour Finals group match despite losing to Novak Djokovic in London this evening.

The British number one now faces a crunch clash with Jo-Wilfried Tsonga on Friday, but insists that the prospect of being knocked out will not be playing on his mind.

"You'd have to play the match and try and win regardless of what situation either of us are in," ESPN quotes Murray as saying.

"I just try and win the match. As professional sportsmen we should be able to deal with all those sorts of situations, be able to focus and concentrate regardless of the situation."

Djokovic defeated Murray in three sets to avenge his US Open final defeat at the hands of the Scot.
