Both Sanchez and Pastore have been heavily linked with big money moves this summer after each enjoyed an impressive 2010-11 campaign with their respective teams.
A number of major European clubs have been linked with a move for the 22-year-old Sanchez including Inter, and Moratti now suggests they are making progress in their approach for the Chilean.
"It's hard to give a precise reply at a moment in which we are trying to figure out if the clubs will sell, how they will sell, the prices, wages and whether certain exchanges will be able to be made,” said Moratti, according to ESPNSoccernet.
"However, let's say that the player with whom we are speaking, and I don't know the odds of our success, is certainly Sanchez, because we've been talking about it for a long time. Also because he's a player with many qualities and because we've opened a certain kind of discussion with Udinese.
"Let's say not that he's definitely coming but [that] there is a 60 per cent chance that he will arrive."
Regarding Pastore, Moratti stated: "We all know that Pastore is excellent, he also played well against us in the Coppa Italia final [that Inter won 3-1], but I don't think that negotiations are possible.”
