Thomas Sorensen is hopeful of playing at the top level beyond the end of his recently-extended contract with Stoke.
Goalkeeper Sorensen will be 38 when the new deal he signed on Tuesday comes to an end in the summer of 2014.
He told BBC Radio Stoke: "I've said all along that I'm really happy at Stoke because it's a fantastic club.
"I don't want to put an expiry date on my top-flight career. It's whatever the body says. If I'm good enough, I'll play as long as I can."
Fellow keeper Asmir Begovic agreed a new four-and-a-half year contract on the same day that Sorensen committed himself to the Potters for another two-and-a-half years.
Sorensen has played the last six Premier League matches, including Wednesday's 3-0 defeat by leaders Manchester City, after regaining his first-team place from Bosnia international Begovic.
"There's competition for the goalkeeping spot," added the former Sunderland and Aston Villa man, who has won 99 caps for Denmark.
"Whoever is playing, it's up to that person to keep the shirt. That's all you want, and now I'm in the team, it's up to me.
"It's great that you've got someone behind you who's pushing and doing whatever they can to get in the team.
"It makes me better, it makes Asmir better and it makes (current third choice) Carlo Nash better. Without that, it would be boring."
Sorensen will come up against one of his former clubs on Boxing Day, when Villa are the visitors to the Britannia Stadium.
