Barcelona have finally registered forward Dani Olmo, leaving the Spaniard free to make his debut against Rayo Vallecano on Tuesday.
The 26-year-old signed for Barcelona, who he played for at youth level, on 9 August but missed the club’s first two La Liga games.
Olmo was unable to be registered because Barcelona did not have the spare funds within the Spanish top-flight’s strict financial rules.
Barcelona released midfielder Ilkay Gundogan back to Manchester City last week and have also loaned defender Clement Lenglet to Atletico Madrid.
Barca have also been helped because of a rule which allows clubs a discount for part of the wages of players who have long-term injuries.
The Spanish club says former Chelsea defender Andreas Christensen will be out for four months.
