Marotta can say whatever he wants (btw, of course he wont say we'll buy the players regardless of how they perform, get long term injuries etc, because that could make the players complacent and he will use a negotiating tool to lower the price if the players completely underperform), but I'm 99,9% sure that w.e're buying Matri at the end of the season, as well as Quaq and Pepe. Only ones I'm not sure of are Aquilani and Motta.
As someone said, regardless of Marottas statements, why would Cagliari loan loan one of their best players for 2.5 mil €?
