Mor has only made 39 appearances for Celta in his three years at the club, with a return of one goal and three assists.
The La Liga side don’t want Mor back for pre-season training and have no idea what to do with him.
Once considered one of Europe’s best young players, Mor now finds himself unwanted after poor form and disciplinary problems.
Celta are aware that no club will be willing to invest much money in Mor, who has two years left on his contract.
As a result, the Galicians are looking for a new club to take the attacker on loan.
