Andy Murray has acknowledged that he still faces a tough task trying to overhaul Novak Djokovic at the top of the men's world rankings.

The 29-year-old won his seventh title of the year on Sunday as he eased past Jo-Wilfried Tsonga in the final of the Erste Bank Open in Vienna.

That straight-sets win ensured that Murray remains on track to end the season on top of the pile, with victory at next week's Paris Masters - coupled with Djokovic failing to make it to the final - enough to see him usurp the Serbian ace.

"I get a step closer with every win but it's still a long way from here," he said after his latest triumph. "From two to one seems a small jump in a way but it's the hardest one to make. To go from 100 to 50 is more spots but is a lot easier."

Murray has now won three titles in a row following recent successes in Beijing and Shanghai, losing just three matches since the French Open in June.
