UEFA president Aleksander Ceferin says Diego Maradona "set football alight and thrilled fans young and old" and confirmed his death would be marked with a minute's silence prior to all Champions League and Europa League games this week.
The Argentina great, who played for Barcelona, Napoli and Sevilla as well as Argentinos Juniors, Boca Juniors and Newell's Old Boys in his homeland, died aged 60 after reportedly suffering a heart attack on Wednesday.
Ceferin said: "I am deeply saddened to hear of the death of Diego Maradona, one of world football’s greatest and most iconic figures.
"I was in touch recently to wish him well, and this news comes as a considerable shock to me.
"Diego Maradona achieved greatness as a wonderful player with a genius and charisma of his own. He was a hero in his native Argentina, with whom he enjoyed World Cup glory, and became an eternal idol for the supporters of Napoli, who will never forget the successes he brought to the club during his memorable spell in Italy.
"He will go down in history as someone who set football alight and thrilled fans young and old with his brilliance and skill. I have instructed UEFA to hold a minute’s silence in memory of Diego at this week’s matches."
