Actually Marotta agreed with this decision, as he said one month ago, and was one of those that pushed for this. Probably tired of having to pay to get the full ownership for fucking small clubs that want to boss around (Parma for Giovinco, fe, but soon also Berardi, Gabbiadini, Rugani, Marrone) for players that have to spend just 1-2 seasons away. A simple loan, that can also be renewed, will do that.
