Southampton are demanding £15m for right-back Nathaniel Clyne this summer, according to reports.
The 24-year-old is out of contract next year and has been linked with a move to Liverpool, who reportedly had a £10m offer rejected last month.
However, The Telegraph claims that the Reds will have to offer an extra £5m if they want to snap up the England international, who is yet to tell the Saints if he wants to leave or not.
Clyne is likely to have competition if he stays at Southampton, after the club announced that they have signed Cedric Soares from Sporting Lisbon.
