Cardiff City want £10 million for goalkeeper David Marshall.
The Daily Star says the Championship play-off contenders are desperate to hold on to the Scotland international, who has two-and-a-half years remaining on his contract.
Everton were thought to be weighing up a move for the 30-year-old with Tim Howard struggling for his best form, while West Brom made efforts to land Marshall last summer.
The former Norwich keeper was the star of Cardiff's sole Premier League season, making the most saves of any top-flight stopper, and has been back to his best so far this season.
But manager Russell Slade knows losing his number one would have a detrimental effect on Cardiff's promotion hopes, although the Welsh club know they may struggle to hang on to Marshall come the summer should they fail to return to the Premier League.
