The 34-year-old goalkeeper has backed himself to continue his fine form for his country at the World Cup regardless of his club form
Cesar has established himself as Brazil's number one shot-stopper after his selection was questioned as a result of the 34-year-old now playing for Toronto in MLS.
But the veteran says he is a firm believer in his own abilities and pointed to a crucial save he made in the draw with Mexico to keep his side on track for the last-16.
"I have made it clear that I really primed myself for this World Cup regardless of the fact that some critics did not agree with my choice of going to play in a league that is in theory not strong," he said.
"I can look in the mirror and say I believe in myself. I made an important save against Mexico to help us get a draw and physically and mentally I am prepared."
The Selecao continue their World Cup campaign on Monday in their final group game against Cameroon.
