Victories over Colombia and Ecuador have helped Neymar and Dunga to relieve some pressure on the team's shoulders following the World Cup, and the Barcelona forward is convinced that he can be a good leader for the new-look side.
"I am still a young leader, I am one of the younger players here but I am really happy," the 22-year-old told reporters. "These four years I have been learning so many things, from the first day until today and now I can help where I can when we have new players, to make them feel comfortable.
"I think the results here were good. It's very positive because we had two difficult games but we have won both and so we are very happy."
Neymar has won 57 caps since making his debut in 2010.
