Despite his stellar career, Dias was not given a spot on the 1966 FIFA World Cup team, when Coach Feola opted to call up an ageing Zito to the squad instead of Dias.
Furthermore, in 1973, at the age of 30, he suffered a heart attack.
The São Paulo teams he played for were never really contenders—the board opted to spend their money in the construction of Estádio do Morumbi instead of on players.
He earned 27 caps for Brazil.
After many years training and working as coach for the SĂŁo Paulo FC youth team, Roberto Dias suffered a fatal heart attack and died in SĂŁo Paulo.
In his honor, the SPFC team played with a black armband in the second game against Boca Juniors for the 2007 Sudamerica Cup.
