La Liga have registered new Barcelona signings Robert Lewandowski, Raphinha, Franck Kessié and Andreas Christensen.
Jules Koundé has yet to be registered and is expected to miss Barca’s home game against Rayo Vallecano on Saturday.
Sergi Roberto and Ousmane Dembélé, who resigned for the Camp Nou outfit this summer, have also been registered and will be available for selection against Rayo.
In order to register Koundé, Barça will have to either reduce their wage bill or release more players.
In a last-minute turnaround, Xavi will now be able to count on most of his signings for the start of the new league season.
