Andy Murray has said that he is not used to having the middle weekend off at Wimbledon.
The British number one and second seed at this year's Championships will have two days' rest on Saturday and Sunday after completing his third-round match under the Centre Court roof yesterday.
"I'll probably practise a bit longer [today]," said the 26-year-old. "Normally on the days off you practise for maybe an hour. But I'll practise for about an hour and a half and have a slightly tougher practice session. Then Sunday we'll be back to the same sort of schedule.
"I haven't played that many times on the Friday at Wimbledon, so it's a little bit new for me.
"I have no idea whether it makes any difference. Roger (Federer) always played on Monday. He had a pretty good record here. But I don't know if it's got anything to do with the two days off over the weekend."
Murray will play either Victor Troicki or Mikhail Youzhny in the fourth round at SW19.
