Lucas Digne joined the club from Barcelona.
Lucas Digne has asked to leave the club according to the manager.
The France international has not played since December and has drawn interest from several clubs.
Digne didn't want to be here, according to the man.
Italian clubs are also interested in the 28-year-old, who is currently on loan at Everton.
Digne returned to the squad as an unused substitute for Sunday's home defeat by the Seagulls after a disagreement over tactics and his role in the team.
"Digne wants to leave and I want to ask a question to every fan or former player," said the Spaniard. What would you tell a player who doesn't want to be there?
It is easy. He told me what he thought after a couple of conversations.
Sean Longstaff, who Digne worked with when he was the manager of the Magpies, could be the subject of a swap with Digne.
Eddie Howe's side are 19th in the table and have one win all season, but on Friday completed the signing of England full-back Trippier from Atleti Madrid for £12m.
"You need players that really want to be here", said the Spaniard.
"Do we want to try and improve?" he asked. Or just to leave the team behind and manage the egos?
