Real Madrid great Alfredo Di Stefano is in a serious but stable condition in hospital after suffering a heart attack.
The 88-year-old is being kept in an induced coma in the coronary unit at the General Universitario Gregorio Maranon Hospital.
A medical report from the hospital said he was "clinically and haemodynamically stable", but that his condition remained "serious".
According to reports in Spain, Di Stefano was on a street close to the Bernabeu when he had the heart attack. The hospital said the emergency services were able to stabilise him.
The medical report, which Madrid published on their official website, said: "The patient is currently in the coronary unit at the Gregorio Maranon Hospital. He is under sedation, with endotracheal intubation and artificial ventilation, and is being subjected to the relevant clinical trials.
"The patient is clinically and haemodynamically stable, but his condition remains serious."
Madrid said that president Florentino Perez had visited Di Stefano at the hospital.
Di Stefano is one of Madrid's finest ever players. He was central to the club's domination of European football in the 1950s, helping them win the European Cup for five successive seasons from 1956 to 1960.
The Argentina-born forward played for the club from 1953 to 1964, winning eight Primera Division titles.
He is Madrid's second highest scorer in history, behind Raul, with 307 goals in all competitions.
He also had two short spells as coach of the club and is their honorary president.
Internationally, he played mainly for Spain but also represented Argentina and Colombia.
The next medical report will be issued at noon local time on Sunday.
