The Santos boss is of the opinion the young forward is getting to grips with the physical side of the game, having absorbed a strong tackle from USA's Jermaine Jones on Thursday
The 20-year-old was involved in an incident with rival player Jermaine Jones, when the American midfielder went in excessively hard on the Selecao hitman.
However, according to Santos coach Ramalho, Neymar has found a way to cope with aggressive opponents and showcased the new talent of his against the Americans by evading violent challenges.
"He knows he was hit hard but he protected himself well," Ramalho told Globoesporte.
"This [tackle] was very rough, but he is so strong physically and held his own. The American [Jones] was nervous and scared.
"Still, he has to fulfill his role in the selection, which is important for the Olympics in these final stages."
Brazil's next match is later on Sunday, when they take on Mexico at the Cowboys Stadium in Texas.
