Paul Clement has reiterated Swansea's firm stance on the sale of Gylfi Sigurdsson.
While no formal bid has been lodged, Everton are determined to sign the 27-year old.
However, Swansea have slapped a £50m price-tag on their talisman, and Clement says the club will only sell if they believe the offer is suitable.
"Gylfi has been an excellent player here," Clement the official Swansea website.
"He has three years on his contract and if any business is going to be done, it will be done on the terms we want.
"The club recognised his contribution by giving him an extended contract last season. He was happy to stay on here.
"At the moment he is a Swansea player and we have to carry on looking at it that way."
