Barcelona coach Xavi has admitted frustration with Jules Kounde not yet registered.
Barca need to raise €20m from sales to make room in their wage cap for Kounde to be registered with the LaLiga.
After victory at Real Sociedad, Xavi said: "It bothers us all.
"Mateu (Alemany, director) is doing an extraordinary job. It bothers me because it's important, Mateu must be upset.
"The work he is doing for the club is extraordinary. It bothers me that he is training well and can't even play. Let's wait for next week."
