Argentine football legend Diego Maradona has died at the age of 60, his spokesman announced on Wednesday. Renowned with Brazil’s Pele as one of the greatest footballers of all time, the Argentine World Cup winning captain died of a heart attack, having undergone brain surgery earlier this month, a member of his entourage told.

He suffered a heart attack at his home in the outskirts of Buenos Aires, Argentinian media and acquaintances of the former player said.

Maradona won the World Cup with Argentina in 1986.

Argentine President Alberto Fernandez declared three days of national mourning after the news of Maradona’s death.

Retired Brazilian football star Pele mourned his death.

“Certainly, one day we’ll kick a ball together in the sky above,” he said in a brief statement provided to Reuters by a representative.
