Swansea manager Garry Monk has confirmed the club are in talks with captain Ashley Williams about a new contract.
Wales international defender Williams has been a reported target for Swansea's Premier League rivals Arsenal and QPR.
But Monk says he is hopeful that both Williams and World Cup-bound striker Wilfried Bony will remain with the Swans.
"We are in negotiations with [Williams'] representatives and trying to put a deal across so that Ash will be here for the future of the club," Monk told the South Wales Evening Post.
"I know Ash wants that, I want that, the club wants that, and that's what we are working towards as we speak."
As for Ivory Coast forward Bony, Monk added: "I spoke to him at the end of the season and he knows how I feel, he knows how the club feels, he knows what I expect from him.
"I just want him to concentrate on the World Cup, have a good World Cup and he will be coming back as a Swansea City player."
Midfielder Leon Britton, meanwhile, has signed a one-year contract extension at the Liberty Stadium.
Britton 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.
