The Swans captain, 28, who has two years remaining on his current deal, admits things could not be going any better at the Liberty Stadium.
He said: "It's a boost and always nice to be wanted. It is early days and we haven't got down to talking about it.
"But there's no rush as Swansea know me. I've been here five years and they know I'm not bothered about contracts. I just get on with the job.
"How could I not be happy at the minute? It's been a great start, in fact perfect. I'm captain and I'm enjoying it.
"If the contract is right for me to sign now, then I'll sign it. If it's not, then I won't sign it. It's no big deal or pressure. I may sign it in the future. At the minute I'm happy."
