The 19-year-old has also been strongly linked with the likes of Manchester United and Chelsea.
Moratti said on the club’s official website: “Yes we have but the progress that has been made is to see whether or not there is a chance (to buy the player).
“Now we have to see if we can manage to carry it out.
“These are things that have to take place by putting everything together, which also means taking a look at our revenue.”
Sao Paulo are reportedly looking for offers above £30million for the winger.
“He (Lucas) is a player that has great talent,” Moratti said. “We are watching him closely.”
