My personal experience of some of the wonderkids mentioned on this game. I manage AC Milan so my number one priority was to ensure that my ageing players had capable successors.
I signed Banega for Milan. He is indeed excellent, although he plays only for my second team (i tend to play only players with 95%+ condition, so he still gets a fair amount of games). He is indeed a good, dynamic, deep-lying midfielder, although he cannot dictate play the way Pirlo does (it's ok as my playmaker then becomes Nasri).
Alex Pato has been loaned off to Benfica as he fails to perform in front of goal, and creates less than he ought. We'll see if first team for a full season helps him out.
Nasri is excellent, I bought him for just 3m more than I sold Gourcuff, and while the latter had better stats Nasri can be relied on to pass well throughout and for the odd moment of genius.
I signed Lulinha before i ever learnt that he was a -10, but when the transfer came through (when he turned 18, some bizarre new italian rule), I'd filled my quota of non-EU with Banega. He then signed a new contract and now I must shell out a good 7m for his buy-out clause
Criscito was purchased from a cash-strapped juve but at 14m I reckon it's worth shelling out the extra money on Kompany, because criscito plays solid but unremarkable.
