Celta Vigo sacked coach Antonio Mohamed on Monday and replaced him with Portuguese Miguel Cardoso after a poor start to the season that has left them 14th in La Liga.
The Galician club have three wins from 12 matches and lost 4-2 at home to European champions Real Madrid on Sunday under Argentine Mohamed who replaced Juan Carlos Unzue in May.
Mohamed managed several prominent clubs in Mexico before going to Celta. He won league titles with Club America and Tijuana, as well as a cup title with Monterrey.
Cardoso left Nantes at the start of October after four months at the Ligue 1 club following an impressive campaign at Rio Ave in his native Portugal last season.
He had previously worked as an assistant coach at Deportivo La Coruna, Celta's local rivals, between 2012-13.
"[He] had a splendid season in charge of Rio Ave, taking them to their best finish in the Portuguese league, qualifying them for the Europa League," Celta said in a statement.
