Brazil's 1970 FIFA World Cup-winning captain Carlos Alberto has died of a heart attack, aged 72, with former club Santos leading the tributes.

Widely regarded as one of the finest defenders of all time, Carlos Alberto is most fondly remembered for scoring the stunning fourth goal in Brazil's 4-1 final win over Italy at Mexico 1970.

A sublime team move, that concluded with a thunderous finish after Pele rolled a pass nonchalantly into the right-back's path, sealed a third world title for Brazil, allowing it to keep the Jules Rimet Trophy that Carlos Alberto hoisted at the Estadio Azteca.

Pele paid a warm tribute to his captain and team-mate in Rio de Janeiro on Wednesday (AEDT).

The pair also played together for Santos in their homeland and New York Cosmos in the North American Soccer League.

"I am saddened by the death of my friend and brother Carlos Alberto, our dear 'Capita'," a statement released by Pele read.

"I remember the times we were together in Santos, the Brazilian national team and the Cosmos, forming a winning partnership.

"We were champions for Santos, the Selecao and the Cosmos. Unfortunately we have to understand this and that life goes on. To his family I send my condolences."

The Brazilian Football Confederation (CBF) joined Santos in declaring three days of mourning in tribute to Carlos Alberto's passing.

"With a heavy heart, the CBF regrets that the world of football had been surprised this Tuesday by the passing of Carlos Alberto Torres," read a statement from the organisation.

"A legend for the Brazilian national team, the captain of the third World Cup title in 1970 died in Rio de Janeiro, the victim of a heart-attack. 

"The CBF president, Marco Polo del Nero, has declared three days of mourning. Flags at the CBF will be at half-mast. All games in competitions organised by the CBF will have a minute of silence."
