Barcelona's director of institutional relations Guillermo Amor says the Spanish Federation (RFRF) have still not notified the club if they have permission to sign a player outside of the transfer window.
After Ousmane Dembele was ruled out for six months, the Spanish champions made a request to turn to the transfer market as they have been left depleted in attack -- Luis Suarez is also out for several months.
"A lot's been said but we still don't have the green light from the RFEF to sign," Amor explained. "We've still not received anything official. If we do, the club will take the decision that has to be taken."
Amor continued: "First we have to see if we get authorisation. What's clear is that the club's been working on this a lot. We work every hard day, analysing and improving and, when the moment comes, we will do what's best for the club. That's not in doubt."
