I've sold Frey, Mutu, Gamberini, Pazzini, Pasqual and a few others. Didn't want to sell any of them really, but I had a poor first season and they were getting unhappy and I got a lot of cash for them.
I'm doing better now in my second season (3rd atm) and I have replaced all of them exept Pazzini. I'm playing a 4-2-2-2 without wingers and Montolivio and Rossina are my starplayers on AMC. I got Sobis and Lupoli up front, both doing good. Donadel and Kuzmanovic are bossing the midfield. In goal I have.... uhm... some italian guy

don't remember his name now. In defence I use Balzaretti, Danelli, some russian dude, and Ujalufsi. My squad is a bit thin, especially up front, but I've got £35M to fix that now
