"I'm 35 in September but I feel there is plenty left in the tank for me to play in the first team and have an effect on the team..." the midfielder told the club's website (www.swanseacity.com).
"My idea is to stay at the football club. I've spoken to the chairman and manager about the time when I do finish playing football and I can stay at the club as a coach.
"At the moment my main focus is as a player and giving everything in that respect."
The Englishman's new contract also includes an option for a one-year contract extension along with a guaranteed coaching role at the club after his retirement.
