“There were a lot of positives to be drawn from the match. I don’t care about the quality of the opponent,” he said at the post-match press conference after the first of five tune-up games on home soil before the World Cup opener against Mexico on June 11.
“It’s a big improvement. We are now in our final stage of preparations and we are looking for performance and results.
“Results build confidence and as for the performance, the players look more comfortable on the ball. We still need more penetration but I feel it is coming,” the Brazilian said.
“We now have stronger opponents coming and they will give us a more physical challenge. We are in the final build-up phase but this is a good start.”
Parreira said the game against Bulgaria, Colombia and Denmark would all be progressively tougher.
