"I saw Trezeguet training with Ranieri yesterday," Cobolli Gigli revealed.
"I think the argument was resolved by Jean-Claude Blanc's declarations after the game on Saturday.
"We need to be strongly focused at the moment and I hope that Trez will train hard and be ready when Ranieri calls upon him."
There have been rumours in the Italian Press that Milan are plotting a bold swoop for Juve striking star Amauri.
"It's just talk," Cobolli Gigli insisted. "Amauri isn't for sale - he is one of our great champions, like Trezeguet.
"They are very important to this club and their futures are linked to the club.
"As for summer signings, there is a list and Blanc is working on that with Alessio Secco. Clearly the first thing is to look for a replacement for Pavel Nedved."
