Barcelona are prepared to take their bid to register Turkey playmaker Arda Turan to the Court of Arbitration for Sport.
As things stand, Barca are unable to register Arda, who they signed from Atletico Madrid in the close season, until January because of a ban imposed on the club by FIFA for breaking rules on the transfer of minors.
However, a serious knee injury to Rafinha last month prompted Barca to ask the Spanish football federation (RFEF) and FIFA if they could replace the Brazil midfielder in the squad with Arda.
Barca were prevented from registering players for two transfer windows, with the ban officially expiring at the close of the last window.
While they would normally have to wait for the new window to open in January, rules stipulate that in emergency cases such as injury, players can be registered outside the scheduled transfer windows.
"The legal department has confirmed that FIFA has not responded to the latest request presented on Friday, the third the club made," Barca said in a statement.
"Given the lack of a reply, an appeal will be presented on Thursday to FIFA's appeals committee as a precursor to an appeal to CAS."
CAS, based in Switzerland, attempts to resolve sporting disputes through arbitration and its rulings carry the same weight as judgments by ordinary courts.
Barcelona are suffering something of an injury crisis, with Argentina forward Lionel Messi and Spain playmaker Andres Iniesta unavailable for selection.
