Nikolay Davydenko may be a fading force but Andy Murray will certainly not be underestimating the Russian when they meet in the first round of Wimbledon on Tuesday.
Davydenko is now 31 and has never been beyond the fourth round at Wimbledon, although London was the venue for the best moment of his career when he won the Barclays ATP World Tour Finals in its first year at the O2 Arena in 2009.
That was the fifth consecutive year the Russian had finished in the top 10 but a wrist injury the following year set him back and he has struggled for form ever since.
Davydenko and Murray have met nine times, with the British number one holding a narrow lead with five wins, although their last match came almost three years ago.
Murray said: "It will be tough. He was in 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 Masters Series.
"It's going to be a tough match. 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."
Wimbledon has a slightly different feel this year with the Olympics to follow at the All England Club only three weeks after the end of the Championships.
Murray is currently the only confirmed member of the British team, but he will not be allowing thoughts of medals to distract him from his grand slam bid.
He said: "There's so many big competitions for tennis players right now with Wimbledon, the Olympics, and then a few weeks afterwards the US Open.
"You really need to make sure you don't get ahead of yourself or start thinking three or four weeks in advance.
"You need to make sure you stay in the present and stay concentrated on Wimbledon. When Wimbledon is finished, then I'll get myself ready for the Olympics."
While Murray is not in action today, several British players are, led by Heather Watson, who takes on Iveta Benesova in a match that is likely to be played on a show court in the evening.
Johanna Konta, the former Australian who was cleared to compete for Britain last month, faces 28th seed Christina McHale in the last match on Court 17 while Naomi Broady meets Lourdes Dominguez Lino.
In the men's competition, 18-year-old Oli Golding, the US Open junior champion, will take on Russia's Igor Andreev on Court Two and Josh Goodall faces Grega Zemlja on Court Three.
