Lampard was again made the scapegoat at Wembley on Wednesday when he was substituted during the dismal 2-2 friendly draw with Czech Republic.
Scolari said was baffled by the reaction and revealed he had spoken to the 30-year-old and told him to forget about his international detractors.
"In England? In the national team? I don't believe it," he said.
"I don't believe this because Lampard tries to do the best job for the national team and for Chelsea."
The Stamford Bridge boss added: "It's not one player that makes a team, it is 11. I think England have very good players and Lampard is one of these players."
