Former Spain coach Luis Aragones has died at the age of 75, the Spanish Football Federation (RFEF) has announced.
Aragones was a prominent figure within the national game and led Spain to victory at Euro 2008, beating Germany in the final before ending a four-year spell at the helm.
He was also a successful coach at club level most notably with Atletico Madrid, leading them to the La Liga title in 1977 as well as three Copa del Rey trophies.
A statement from the RFEF read: "The Spanish Football Federation wants to express its grief and shock at the death of Luis Aragones, former player and coach of several Spanish and global clubs and the Spain national team at the beginning of their glorious success on the worldwide stage.
"Luis Aragones led the Spanish team to victory in the 2008 European Championships. He died today in Madrid Clinic, where he had been admitted."
Reports in the Spanish media said Aragones was admitted to the Madrid clinic in the early hours of Saturday morning but died soon after.
Atletico posted a tribute to their former coach on their official website, and will mark his death with a minute's silence ahead of the Primera Division clash with Real Sociedad on Sunday.
"One of the greatest Rojiblancas legends has left us," read the statement.
"There have been condolences from around the footballing world. Our president, Enrique Cerezo, expressed his sorrow saying: 'Luis Aragones was a great player and coach, but above all a great person and a friend. On behalf of the whole club, I want to express our condolences to his family'.
"The club have decided to hold a minute's silence in his memory ahead of the next match against Real Sociedad, in which the players will also wear black armbands in his honour."
