Sky Sports understands that a host of Premier League clubs have Swansea's Ashley Williams on their January wish lists.
The Wales international continues to impress during his second season at Premier League level, displaying the kind of consistency which appeals to potential suitors.
The likes of Liverpool, who are now bossed by former Swans manager Brendan Rodgers, and Newcastle United are believed to be long-time admirers of Williams.
A number of other sides are also weighing up the merits of an approach when the transfer window re-opens.
It is easy to see why Williams is generating so much interest, with the centre-half topping the defensive charts for blocks, interceptions and pass completion.
Swansea would be loath to part with such talent, and they have Williams tied to a long-term contract.
They could, however, find themselves in a difficult situation if a big-money offer were to be put on the table in the New Year.
