The 53-year-old Argentine played for Betis between 1983 and 1987 and arrives having most recently taken charge of the Bahrain national team.

"Humberto Calderon is the new coach of Real Betis Balompie," said a statement on the club's website.

"The coach, who arrived in Seville this evening, has already signed a contract for the rest of the season and an extra season should the club stay up."

Garrido was sacked after winning just twice in 10 games in charge during his two-month long spell in charge.

However, both victories came in the Copa del Rey and after being eliminated in that competition by Athletic Bilbao on Wednesday, their 5-0 thrashing at home to Real Madrid on Saturday was the final straw as it left Los Verdiblancos eight points off safety.

It is the second time this season that Betis have sacked their coach after also dismissing recently appointed West Bromwich Albion manager Pepe Mel in December.
