Swansea captain Leon Britton has signed a new one-year deal at the Premier League club.
Swansea say Britton's new contract is an improved one-year deal, which also has an option for a further 12 months - depending on an appearance clause - and that he also been guaranteed a coaching role within the club once he has finished his playing career.
The London-born midfielder, who turns 35 in September, joined Swansea on loan from West Ham in December 2002, before making the move permanent the following summer.
And, apart for a six-month spell at Sheffield United at the start of the 2010-11 season, he has been with the Swans ever since and has made over 520 appearances for the Welsh club, which has risen from League Two since his arrival.
Britton told the Swansea website: "I felt strong at the end of last season.
"Even when I wasn't playing, I was training well and keeping fit.
"If that wasn't the case then I would know and I wouldn't put myself through that. I would make sure I ended at the right time.
"The club has improved my terms for this season, but there is an option where I can have another year if I play a certain amount of games.
"So, it's potentially a two-year deal, but that depends on how many games I play."
Swansea chairman Huw Jenkins hopes Britton will stay with the club for a while yet.
"He is a model pro and we are very proud to say he is representing Swansea City," said Jenkins.
"He has made a tremendous contribution to this club, both on and off the pitch, over the last 15 years.
"I hope this new contract paves the way for Leon to remain with us for many more years to come."
Britton played an influential role as Swansea finished last season strongly to escape relegation.
Having been overlooked since New Year's Eve, he started the last five games, which yielded 13 points from a possible 15.
Britton was also responsible for the plan that saw the squad put in £70,000 to fund supporters' tickets for the crucial clash at Sunderland on the penultimate weekend of the season.
Swansea won the game 2-0 and their top-flight safety was secured the following day when Hull lost at Crystal Palace.
