Reports in the Spanish media claimed Aragonés was admitted to the Clínica Cemtro de Madrid on Friday but died the next day after losing a battle against Leukaemia.
"It was cancer and Leukaemia which took him from us," Doctor Pedro Guillén told Cadena COPE.
"He suffered several relapses and was admitted to hospital a number of times during the past two months and his condition gradually weakened him.
"He was relaxed about his condition and resigned about what to expect. He didn't suffer greatly because it wasn't a lengthy battle but he did suffer."
Nicknamed El Sabio de Hortaleza (The Wise Man from Hortaleza), Aragonés will mostly be remembered for leading Spain to victory at Euro 2008 and paving the way for a golden era in Spanish football.
While Aragonés stepped down after the tournament, the team went on to win the 2010 World Cup and Euro 2012 under his successor Vicente del Bosque.
He was also a successful coach at club level most notably with Atlético Madrid, leading them to the La Liga title in 1977 as well as three Copa del Rey trophies.
A statement from the Spanish Football Federation read: "The Spanish Football Federation wants to express its grief and shock at the death of Luis Aragonés, 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."
Tributes to Aragonés have also been flooding in on Twitter, particularly from the Spain players.
