Xerez have named Nestor Gorosito as new coach.
The Primera Division strugglers have been managerless for the past week after sacking Jose Angel Ziganda following a miserable start to their first-ever top-flight campaign.
They picked up a point at fellow strugglers Real Zaragoza at the weekend but are now nine points off safety.
Gorosito becomes Xerez's third coach in less than a year, Esteban Vigo having left the club in the summer soon after leading them to the Segunda Division title.
Gorosito's only European stint was the three years he spent as a player at FC Swarovski Tirol in Austria.
The 45-year-old took his first training session on Tuesday.
