Swansea live updates
Leon Britton has signed a one-year contract extension at Swansea.
The midfielder had two years left to run but has now had another 12 months tagged on.
The 31-year-old has made 467 appearances for the Swans since signing for them in 2002, with his only break coming with a brief spell at Sheffield United.
Swansea chairman Huw Jenkins feels a "shake-up" is needed at the club this summer, with players definitely good enough to be first-team starters coming in and "new motivation" being cultivated.
The Welsh outfit already have a new permanent manager in place with Garry Monk, in temporary charge since the dismissal of Michael Laudrup in February, signing a three-year contract last week.
– Swansea chairman Huw Jenkins.
I think a shake-up is needed - and whatever number we manage to bring in, whether it's two, three, four or five players, they need to be first-team starters. That's where we are at.
It's all well and good having 20, 25 players in the squad, but we need to improve the starting XI - and I don't think anybody would argue with that.
Some people have said we signed too many players from Spain last year, but ultimately it doesn't matter where they come from, as long as they are good enough it will be fine.
Swansea have announced the release of strike duo Leroy Lita and David Ngog, while Roland Lamah and Alvaro Vazquez have returned to their Primera Division parent clubs.
