The 27-year-old Texan suffered his most recent defeat there earlier this year when he was beaten in the final by Roger Federer as the Swiss player won a record 15th Grand Slam title.

 

It followed final defeats there in 2004 and 2005, when he was also beaten by Federer.

 

Roddick said: "I certainly look at that 2012 year, the prospect of playing an Olympic event on grass, it's very interesting for me."

 

Roddick's only appearance in the Olympics came at Athens in 2004 when he was knocked out in the third round by Chilean Fernando González, the eventual bronze medallist.

 

He plans to be a contender in London in three years, although Federer has already declared that he hopes to win the Olympic singles title that has so far escaped him during his brilliant career.

 

Roddick said: "Certainly I feel like or at least I hope there will be many good memories still for me here in London."

 

Roddick, whose career earnings are $16.9 million (£10.1 million), including winning the US Open in 2003, is in the capital to watch the ATP World Tour Finals at the O2 Arena which he has been forced to miss because of a knee injury.

 

He said: "To be able to come here and see just the energy that's around it, just the great event that's being put on, I definitely am envious toward those guys out there, that they're able to play and participate in this event."
