Captain Lucio has voiced his concerns over Brazil's defensive lapses at the World Cup but insists they are not planning any special tactics to quell the threat of Cristiano Ronaldo.
The five-time world champions are preparing to conclude their Group G campaign against Portugal on Friday and they require only a draw to reach the knockout stages as group winners after victories over North Korea and Ivory Coast.
Brazil manager Dunga has introduced a more cautious approach to his side in comparison with the Samba stars of the past and it is still proving productive, but the South Americans have been conceding sloppy goals.
Lucio is not panicking, however, he is eager to keep a first clean sheet of this summer's World Cup against the Portuguese in Durban.
The Inter Milan centre-back said: "No-one likes to concede goals, but there is no need for drama.
"We always need to try to improve and seek perfection, and we hope the mistakes don't happen again from now on."
He added: "We have been talking among ourselves (about the mistakes). Of course we are not satisfied with the goals, but they came at a time that we could allow them."
Ronaldo will pose a significant threat to Brazil after helping Portugal to a 7-0 thrashing of North Korea, but Lucio claims that the world's most expensive player is not a special case.
"Without a doubt he is a great player, he has been showing this for a long time," he said of Ronaldo.
"We need to try to defend as a team, it's key we help each other and stay focused. We will have to pay attention to a player like Ronaldo and also to the others."
