Osasuna have sacked coach Enrique Martin after a slow start to the season which sees the club lie second from bottom in the standings.
The Pamplona-based club have only one win from their opening eleven league matches and Saturday's home defeat to Alaves left them 19th in the table with only seven points.
The 60-year-old has a long association with the club, having made over 250 first-team apperances between 1977 and 1988, while this was his third stint as manager after also overseeing the Osasuna B and youth sides.
"After the meeting this afternoon of the board and the sporting management of Osasuna, the club has decided to relieve from office the coach Enrique Martin," a club statement said.
"After analysing the sporting situation of the team, the club has identified the need to make this decision with the aim of reversing the current dynamics.
"Osasuna would like to thank the effort and dedication of Enrique Martin, whose name will go down in history thanks to his brilliant contribution as a player and coach. The club wishes you the best of luck in your future professional challenges."
