Britain’s Andy Murray is one win away from becoming world number one following Novak Djokovic’s surprise defeat by Marin Cilic at the Paris Masters.

After Novak Djokovic’s quarter-final defeat to Marin Cilic on Friday, Murray knows victory will be enough to lift him to the top for the first time in his career.

It will cap a remarkable rise for the Scot but after dispatching Czech Tomas Berdych in straight sets he insisted on playing down the possibility.

Murray told Sky Sports: “My goal isn’t to get to number one this year – I was looking at the beginning of next year as the chance to do it.

“If it happens this week, great. I’m happy with the way I’m playing just now. It’s been a great few months for me. I’ll try to finish this week as best I can.”

Murray saved seven set points in an extraordinary first-set tie-break before eventually going on to overcome Berdych 7-6 (11/9) 7-5 and book his place in the last four.

Earlier, Djokovic had handed the Scot the initiative in the race for the summit after going down 6-4 7-6 (7/2) to feisty Croatian Marin Cilic.

Djokovic’s hold on the world number one position had looked increasingly precarious after he had required treatment on a knee injury on his way to an unconvincing last-16 win over Grigor Dimitrov on Thursday.
