Luiz Felipe Scolari has said that Brazil are aiming to be competitive and win games at the Confederations Cup.
The host nation will face Japan, Mexico and Italy in the group stage of the tournament, which serves as a rehearsal for next summer's World Cup.
"The team is coming together. I once read in a magazine that nature does things slowly. We need to keep on working to be competitive and win games," Sky Sports News quotes the Brazil manager as saying.
"Most of the players we picked haven't played an official competition with Brazil. Before they can play in a tournament like the World Cup, I need to observe them playing in bigger matches.
"We lose by not having more veterans in the squad, but we gain by having their youth and desire to succeed."
Brazil face Japan in the opening match of the cup this evening.
