Celta Vigo has replaced coach Paco Herrera with Abel Resino after the Primera Liga struggler lost 3-1 at Getafe to remain third-last on the ladder.
Herrera, 59, is the seventh coach sacked from a La Liga club this season.
Resino, 53, has coached Levante, Valladolid and Atletico Madrid among other clubs. He has been out of contract since being sacked by Granada in 2012.
Barcelona will be able to sign players this summer after FIFA announced that the club's transfer ban will be put on hold pending an appeal.
