Atletico Madrid have confirmed they have parted company with coach Javier Aguirre and reached an agreement for Abel Resino to take his place.
Aguirre, who has been in charge at the Vicente Calderon for two and a half seasons, has paid the penalty for a miserable start to 2009 which has seen Atletico lose five and draw two of their seven games.
Resino, the former Levante coach and Atletico goalkeeper who has led Castellon into the top six of the Segunda Division this season, will take charge of the Rojiblancos until the end of the campaign.
Aguirre will offer a press conference at 1300 local time while Resino will do likewise at 1900 this evening.
A statement on the Atletico website read: "Atletico Madrid and the Mexican coach Javier Aguirre have reached an agreement, which has been closed this morning, to resolve the contract which he had as coach of the Rojiblanco first team until the end of the season.
"The club want to thank Javier Aguirre for his work and commitment for the best part of three seasons in which he returned the team to European competition (UEFA Cup and Champions League) and wish him the best, both on a personal and professional level.
"At the same time, Atletico Madrid want to announce they have reached an agreement with Castellon for Abel Resino to become the new Rojiblanco coach until the end of the current season."
Despite his premature exit from the club, Aguirre is proud of his achievements with the Rojiblancos - which include league finishes of seventh and fourth, and qualification into both the Champions League and UEFA Cup.
''I am leaving with a clear conscience, even though I did not complete my work until the end,'' he said at a press conference. ''It has made me proud to be part of Atletico Madrid, a great club in size and in history. We are talking about one of the 12 to 15 biggest clubs in the world.
''It always hurts when there is a break-up, although it is not traumatic. Enrique (Atletico president Enrique Cerezo) has acted superbly.
''We all want Atletico to fulfil their objectives and be great. I thank all the employees at the club, I've never had a problem with anybody.
''I want to thank publicly my players and my backroom staff. It's a club that I carry in my heart and who helped me grow.''
The former Mexico coach also had a message of support to his successor, saying: ''I wish all the best to Abel Resino. I'm sure that at the end of the season the team will have reached the objective of the club, which is to get into the Champions League. I wish them the best of luck.''
