"They can teach us something in terms of the desperation of all their players and pride to play not just for Brazil, but at the Olympic Games," Pearce told Sky Sports.
"If you read articles in this country it is seen as just for taking part, just for fun, just for everything apart from having a real go at trying to win the competition.
"This Brazil team only have one player that hasn't been capped at senior international level.
"That tells you they are not afraid to put their younger players into the main side to gain experience and also that they are taking it seriously."
Along with the likes of Brazil and Spain, Team GB are being tipped to challenge for a medal on home soil and Pearce hopes to enjoy a tournament that the players will never forget.
"When we finish this tournament, we want to send 18 players back to their clubs with a lifetime of memories," he revealed.
"To do that we have to be successful, get out of the group and see where we go from there."
