Skysports.com understands Swansea have rejected a bid from Championship rivals Leicester for Ashley Williams.
Foxes boss Paulo Sousa is keen to be reunited with the Wales international having worked with the central defender during his time in charge of Swansea.
Williams is regarded as one of the best young defenders outside the Premier League and has been linked with a host of clubs.
Sousa is looking to bolster his defence before the transfer window slams shut and he is believed to have tabled an offer for Williams.
However, Swansea have rejected Leicester's overtures as they look to keep Williams at the Liberty Stadium.
