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

Second seed Murray beat Czech Tomas Berdych 7-6 (11-9) 7-5 and will play Canadian Milos Raonic in Saturday’s semi-final at about 15:30 GMT.

Victory would see the British number one top the world rankings for the first time.

Murray claimed the first set after a thrilling tie-break in which he defended a total of seven set points, having at one stage been 6-1 down.

He immediately broke Berdych’s serve in the second set, and looked set to force home his advantage until, when serving for the match at 5-4, his opponent broke back.

However, Berdych failed to take advantage and his double fault handed the initiative back to Murray, who held his nerve for a sixth successive win over the 31-year-old.

“Before the match there were a few more nerves maybe than there was earlier in the week,” said Murray. “But once I got out there, I didn’t feel any different to any other match.

“If it happens this week, great. But if not, I’m not putting any extra pressure on myself this week because I still think I have an opportunity to do it in the future.

“But obviously I’d love to do it tomorrow if I can.”

Murray’s semi-final is scheduled on court not before 15:30 on Saturday.
