Ausilio was speaking before their 1-0 win on Sunday.
“I won't rule anything out, but Pellegri is a talented player and Inter already have young forwards just as talented in house," he said.
Ausilio continued: "It's far too early to say this is a finished project, as there's a lot of work still to be done and we need to concentrate on the details.
“This is a team where you have players like Brozovic, a Croatia international, and Joao Mario, a Portugal international, so there is competition for places.
“Depending on what the Coach decides, there are always 11 players who start and there's quality all the way through the squad."
