Barnsley have made a £650,000 offer for Zwolle left back Kenneth Paal.
The Championship club are still to appoint their new head coach following Valerien Israel’s decision to leave for West Brom last week - but have made Paal a primary target.
The Tykes have submitted their first offer for the 23-year-old and are hopeful of completing a deal for the Dutchman.
The former PSV Eindhoven defender, who made 13 appearances for Holland Under-17s, received rave reviews for his performances in the Eredivisie last season and has attracted interest from a host of clubs.
