Liverpool would reluctantly sell Wales right-back Neco Williams, with a minimum asking price of £10m.
The 20-year-old, who joined the Liverpool academy aged six, would also be reluctant to leave, but has struggled for first-team football with the Reds.
He made just 13 competitive appearances for Liverpool in 2020-21, but is part of his country's squad at Euro 2020.
Any move would depend on who comes in for Williams and how serious they are.
Williams, who signed a five-year deal with Liverpool in August 2020, has made two appearances at Euro 2020 so far for Wales.
