Football legend and former Barcelona player Diego Maradona has died at the age of 60.
The Argentine playmaker, who later managed his country, suffered a heart attack on Wednesday.
Maradona had successful surgery on a blood clot in his brain in November.
"A very sad day for all Argentines and football," said Lionel Messi on Instagram. "He leaves us but does not leave, because Diego is eternal.
"I keep all the beautiful moments lived with him and I send my condolences to all his family and friends."
Argentina has declared three days of mourning for the legend who played 91 times for them, playing in four World Cups.
"You took us to the top of the world. You made us immensely happy. You were the greatest of them all,” said president Alberto Fernandez.
"Thank you for having existed, Diego. We're going to miss you all our lives."
Maradona, who struggled with cocaine and alcohol addiction, retired in 1997 as a player at 37, before later coaching Argentina. He was currently coach of Gymnasia and Esgrima, an Argentine top flight team.
