Now FIFA have written to all national associations to explain that players who were not employed by any club when the window closed at the end of last month can move before it reopens in January. In the letter, FIFA say: "The strict application of the transfer registration periods would cause serious inconvenience to players still looking for a club to sign them on, since on the one hand they would have no income and on the other they would not be allowed to register for a new club when the official transfer window has closed."
