Manchester United have received an €11m (£9.7m) bid from Real Sociedad for Adnan Januzaj.
United are considering a number of offers for the Belgian winger.
Januzaj made 27 appearances under David Moyes in the 2013/14 season but since then he has been sent out on loan by Louis Van Gaal and Jose Mourinho.
Januzaj spent last season on loan at Sunderland. He played 25 times without scoring as Sunderland finished bottom of the Premier League.
It is likely the club will insist on a sell-on clause and a buy-back option in any deal, similar to the ones installed in Memphis Depay’s contract when the Dutchman was sold to Lyon in January.
