Former Roma star Falcao has spoken about the form of two of the club's Brazilians this season.
Falcao said: "Cicinho is an attacking wing-back, which can count against him in a defensive system. I am sure (coach) Luciano Spalletti will allow him to express his talent.
"Rodrigo Taddei is a great player, but frankly would struggle to carve out a space in the Selecao, because in Dunga's team he would have to compete with Ronaldinho, Robinho and Kaka."
