De Sciglio,Silvstre, Bonera, Montolivo, Kaka, Stephan , Pazzini, {Saponara not fully fit}, and Mario suspended. I'm sure there are more, just can't think of them right now.
When we got Matri, he was a player who was in hot form and was Cagliari's top player. So no way they were going to let him go for cheap. When we sold Matri he was a bench player who we barely needed. Getting 12 million for him was a fucking steal.
