aquilani should be a first priority imo. The question is whether or not we should sacrifice iaquinta. Now, after considering our financial position, i think we won't ever be able to get aquilani for cash only. Roma do have some financial power for themselves (although their salary cap will kill them soon) and they surely won't let go a promising youngster just like that. So i'd say there would have to be a juve-player going to other way. Now i don't like throwing away like that someone like iaquinta, but in my opinion, the situation is pretty clear. Iaquinta is on a good level right now (higher than palla). He performs solid, scores his goals. all in all decent and solid pretty much every time he's called. But iaquinta has reached his peak imo. There is not much room for him to improve. With palla this is somewhat different.
I'm conviced that palla has the talent to become one of italy's top players. He lacks experience, he lacks the 'easy thinking' and he simply lacks game practice but those are things that can be fixed, and i do believe that palla can be way more useful than iaquinta, if he's given time. Palla could also turn out more versatile, playing more as a winger maybe, or even behind 2 strikers.
So all in all i'd have to say that i would hold on to palladino and, with some regret, give them iaquinta and some money. The question that necessarily comes up is of course "is aquilani worth it" and i do belive he is. Fact is, he's one of the most promising CM/AM in italy, he's young, he's technically good, he's serie-a-proven, and i think he's even called into NT. And let's not forget; in our system with a dentral midfield more CM than AM, he'd be very useful. I think he fits our play the best.
I really hope he comes although i have to say that i don't quite believe in it yet. Too many 'maybe's and 'perhaps', but i'd definately aim for this boy. he's the future of italian football, together with the players we already have (palla, chiellini, giovinco, lanzafame, ... )
