BUENOS AIRES: Argentine football legend Diego Maradona has died at the age of 60, his spokesman announced Wednesday. Renowned along 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 AFP. President Alberto Fernandez immediately announced three days of national mourning in the South American country. "Rest in Peace, legend of football," tweeted Brazil idol Neymar. His message was accompanied by a black and white photo of Maradona from his playing days with Neymar as a boy.
