Ganso has declared he expects to join Inter in 2011, while coach Leonardo has admitted he'd like to see the youngster signed.
But Moratti warned: "There is not only him in South America, and yet he already has a high price: it is not an issue to deal with at this time.
"Leonardo spoke well of him, but he speaks well of everyone we discuss."
Moratti also admitted interest in Cagliari striker Alessandro Matri.
"Buying him would be a good idea."
