The flak has been flying around Roy Hodgson's squad after a disappointing draw against the Republic of Ireland in midweek.
But the Chelsea midfielder, England's skipper in the Maracana, insists the squad can cope, even if they are not packed with the star names that made up the team for his first major tournament, Euro 2004.
Lampard said: "There is a very positive feel among the players. I feel as positive as I have for quite a while in an England squad, because mainly of the emergence of the youth and the pace in the team which is, I think, a big threat we hold and we want to use that threat.
"It's difficult to compare to 2004. We went into that tournament with a very confident squad and with more established names.
"In the modern game and particularly from the last World Cup forward we have been crying out for the emergence of exciting youth. So there are players there that are maybe not as established as Michael Owen might have been but their name is there to be made for each of them.
"I am certainly confident, and the manager and I think the squad is that there are lads that are going to make a name for themselves and possibly will be peaking at the perfect time."
Lampard said missing out on qualification for Euro 2008 was perhaps the lowest point of his career and he is determined not to let that happen again.
He added: "We are not stupid, we are under no illusions. We know we have dropped a couple of points in the group and given ourselves four games to get the right result. I am completely confident we have got the team to do that.
"Brazil is a game for us to look at our performance and show we can put on a performance in a real showpiece game against one of the big nations. Show we want to be back here next year.
"An England team never wants to not qualify for a major tournament and one of the worst, probably the worst, moment of my career was not qualifying [for 2008].
"We know there is work to be done to get there whatever group you go into for a Euros or World Cup, and it is up to us to do that."
