Andy Murray believes he will have to be clinical to beat the big-hitting Milos Raonic in the last four of the ATP World Tour Finals in London on Saturday.
The pair will meet in the first semi-final at 2pm at the O2 Arena, with Novak Djokovic and Kei Nishikori following in the second semi at 8pm.
Murray has won eight of his 11 matches against Raonic and all of the last seven, including five this year, but the world No 1 is wary of his opponent's powerful serve and groundstrokes.
He said: "He obviously serves big and 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. Then it comes down to, when you do get those chances, whether you take them or not. This year, when I have played him I have created a few opportunities in the matches.
"When they have come, I have been pretty clinical. I will need to be the same tomorrow if I want to win."
As well as trying to win the tournament, Murray is battling Novak Djokovic to end the year as world No 1. The pair are separated by just 130 rankings points with 400 available for winning a semi-final and another 500 available for winning the final.
Both players avoided each other in the last four by topping their respective groups, but Murray insisted it does not matter if and when he has to play the Serb.
He added: "I don't think it's significant. There is a good chance that if I want to win the tournament, I would have to win against him. That would either be in the semis or the final. I don't think that makes a whole lot of difference."
