It was reported the Giallorossi had a €10m offer rejected earlier this month, but the situation is progressing.
“Bologna want to build the team around him, but seeing as the situation is not terribly rosy, they should listen to the offers coming in for the lad,” said agent Vincenzo D’Ippolito.
“Roma, as is well known, have made a proposal. Now we have to see what Bologna say next week.
“Gaston is very happy with this idea, as he wants to join Roma and challenge himself in such an important club.
“I think negotiations could reach a successful conclusion for €12-13m.”
