Seattle Sounders goalkeeper Kasey Keller believes he will still be playing beyond the end of 2010.

The 39-year old shot-stopper is on the verge of completing his first season in MLS and has helped the Sounders to the play-offs in just their first season in the competition.

Keller, who has represented the USA as a goalkeeper more than any other player in history, is keen to keep going but says he does not want to play past his use by date.

"You never know what is around the corner, but I would feel a little bit surprised if I wasn't still playing that year," Keller said.

"I've said many, many times I don't want to become that guy that everyone said should have retired last year.

"I want to make sure I am able to play at a level I expect of myself and other people as well."

Keller has experienced a brilliant career that has taken him from Portland to Millwall, Leicester City, Rayo Vallecano, Tottenham, Southampton, Borussia Monchengladbach and Fulham.
