Defender Kaine Kesler-Hayden is likely to leave Aston Villa this summer after an impressive loan spell at Preston North End.
The 22-year-old is attracting interest from the Championship and abroad following a standout season at Deepdale.
He has come through Villa's academy - making four substitute appearances - and any cash will help the club comply with Profit and Sustainability Rules (PSR).
Kesler-Hayden, an England Under-20 international, won Preston's young player of the season and player of the season awards.
The full-back made 51 appearances as North End finished 20th in the Championship.
