I'd rather see two new quality fullbacks than seeing Cassano and average fullbacks again like Motta or something like that again.
Giovinco should be the normal choice for the LW, he's has been playing really good so far, been MoM in all the games he has played and has been getting good ratings for his performances this season, also, he wouldn't cost us that much. Problem is that I don't really think he'll be coming back, I think the relationship is beyond repair between him and Juventus right now.
Aquilani,Melo and Marchisio switched roles alot at weekend. Some moving inside/outside at different times. Del Neri can make the midfield unlike Ferrara who stuck him dead on the LW.
I like Quag and he's a decent player but the 15 million we're spending on him, I can't help but think that those 15 million could be used for something else. Also, he's 27(soon 28).
