Andy Murray has said that beating Nikolay Davydenko will be a tough task.

The Scot opens his Wimbledon campaign against the Russian, who has dropped to number 47 in the rankings, on Centre Court tomorrow.

Murray said that he is wary of the former world number three and will have to be on top of his game to triumph.

"It will be tough," admitted Murray. "He was one of the top four or five players for a number of years.

"He's won some big events. He's won the Tour Finals. He's won ­the Masters Series.

"He hasn't played so well this year, but he has a lot of experience and has been a top player for a lot of years."

Murray has been a runner-up at SW19 for the last three years.
