Tributes soon poured in from friends, former rivals and footballers of all generations to a man widely considered as one of - if not the - greatest players ever to grace the game.

Condolences included from five-time Ballon d'Or winner Ronaldo.

"Today I say goodbye to a friend and the world says goodbye to an eternal genius," wrote the 35-year-old Portugal star, sharing a picture of himself smiling alongside Maradona. 

"One of the best ever. An unparalleled magician. He leaves too soon, but leaves a legacy without limits and a void that will never be filled.

"Rest in peace, ace. You will never be forgotten."

Ronaldo's tribute was one of millions from all around the world to a mercurial genius who captivated for his brilliance on the pitch and also burnished his legend with a colorful lifestyle off it. 

Brazilian great Pele, who often vies with Maradona for the label of the greatest of all time, also shared a touching message.

“Certainly one day we’ll kick a ball together in the sky above,” wrote the 80-year-old icon.
