Former Brazil striker Ronaldo has described criticism of Neymar as "nonsense".
The 26-year-old was widely lambasted for some of his playacting when being tackled during the World Cup.
Following his side's 2-0 defeat to Brazil in the last 16, Mexico coach Juan Carlos Osorio accused Neymar of "too much acting".
Ronaldo - who is one place and five goals ahead of Neymar in the list of Brazil's all-time top goalscorers - said: "There are many ways to see football and interpret it.
"I am against all these opinions (on Neymar acting). He is an intelligent player in his movements and on how to defend himself from being tackled.
"I don't think referees have been protecting him enough. When people repeatedly hit me I would feel a sense of unfairness.
"Criticism is nonsense. TV shows and newspapers just want to fill the space."
