Andy Murray aiming for double

US Open champion Andy Murray has insisted that his full attention is on the upcoming Paris Masters.

Current world number one Roger Federer withdrew from Paris to prepare for the London ATP World Tour Finals which start next week, but the Scot has refused to follow suit.

"I'm going to go for it this week and try and play well and have the best finish to the year possible," the Scot told the BBC.

"I know how I felt at the end of last year. It was really tough for me to work all that time to get the chance to play at the O2 and not be able to finish the tournament.

"This year I want to make sure that come the start of that event, I'm 100% ready to go."

Murray is currently ranked number three in the world.
