Former Brazil coach Carlos Dunga says Inter Milan shouldn't expect instant impact from Lucas.
The Sao Paulo star is on the shopping list of Inter president Massimo Moratti.
Dunga told TMW: "He is very strong, very strong. But he is young, this is the first year he plays continuously. He has great potential and everything to succeed.
"He is excellent in one-on-one tackles with defenders. One for the future, definitely."
