Rafael Nadal gave last week's Paris Masters a miss and Novak Djokovic pulled out in mid-event with a shoulder injury, but Andy Murray expects the two above him in the world rankings to be in good shape when the ATP World Tour Finals begin at the O2 Arena in London tomorrow.

"If I had a problem I wouldn't want to show it to everyone, but everyone seems fine," Murray (above) said. "Rafa's going to be fresh, which is an advantage. And I saw Novak at the gym yesterday and he was doing a lot of different exercises. He seemed fine."

Murray himself has been in rare form but the 24-year-old Scot admitted that he had cut down his practice this week after returning from Paris with niggling hamstring and elbow injuries.

The world's top eight players are split into two round-robin groups. Murray faces David Ferrer, the world No 5, in his first match on Monday. "That's the thing that's tough," he said. "There's no time to warm up [against lesser men]."

His other group opponents will be Djokovic and Tomas Berdych, who ended Murray's 17-match winning run in Paris. "I learned things from that match," he said. "Every time you have a match like that [it lasted three and a half hours] and have a lot of chances, I learn some things I can do better."
