Sport report that several Barcelona stars have also urged the club to push forward the registration of Turan following injury to Iniesta, Messi and Rafinha.
FIFA have been trying to block Barcelona from registering the bearded international due to the transfer ban they imposed on the club.
Barcelona and the RFEF however, argue that under Spanish rules a player with a long term injury (Rafinha) can be unregistered and replaced with a player that missed registration over the previous transfer period.
Representatives of 12 Spanish clubs met the RFEF board on Monday and agreed to help Barcelona at the meeting.
In a statement published in Sport (via Cadena Ser), Daniel Barroso, sporting director at Hercules, stated:
“I don’t understand why FIFA will not accept a rule which we have in the country. It’s a rule which benefits a team in a league in which all members understand and accept. I don’t know what the problem is.”
Turan joined Barcelona on a five-year deal from Atletico Madrid over the summer but is unable to play for his new club until the turn of the year under the current FIFA ruling.
The 28-year-old is however, able to play international football and has been picked by the Turkish national team ahead of key Euro 2016 Group A qualification games against Czech Republic and Iceland.
