Andy Murray takes on Canadian fourth seed Milos Raonic in the semi-finals of the ATP World Tour Finals on Saturday.

The Scot, 29, is trying to win the season-ending finale for the first time, and end the year as world number one.

Djokovic takes on Japanese fifth seed Kei Nishikori in the second semi-final at 20:00 GMT.

Murray has beaten Raonic seven times in a row, and five times this year, including in the Queen’s Club and Wimbledon finals.

“It’s a big match,” said Murray, who is on a 22-match winning streak. “Milos serves big, goes for his shots. He moves forward when he has the chance.

“I think he probably likes the conditions here. It’s a little bit quicker.

“You don’t normally get loads of opportunities against the big servers. This year when I’ve played him, I’ve created a few opportunities in the matches.

“When they’ve come, I’ve been pretty clinical. I’ll need to be the same tomorrow if I want to win.”
