Inter are turning to the 20 year-old after being rebuffed by Udinese in their bid for Alexis Sanchez.
"I can say Inter and Bologna have spoken and there was certainly contact between the clubs," agent Vincenzo D'Ippolito told FCinter1908.it.
"[Ramirez] would certainly be interested in wearing the Inter shirt. Every player wants to achieve the maximum in their career. Inter would be the best for him."
Bologna have yet to make their fee demands, but the agent believes his client is worth as much as €15m.
"I don't know how much value the player has, but as an expert I believe Gaston is worth around €15m," said the agent.
