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.
Real Sociedad coach Philippe Montanier is to leave the Primera Division side at the end of the season after turning down a contract extension, the Basque club has confirmed.
