That last sentence makes no sense at all, I have no idea why you're comparing them like that.
Wel, as you said we should buy players and the formation later right ?
wel, then we'll label both "SS/CAM"
and i just pointed out that there isnt really anything in wich pastore is superior.
but i disagree with this whole matter, you need a base formation, and then buy players in function of that formation. if neccecary the coach can bend it, but you need a base to start from.
and any formation we could field, would prefer aguero over pastore, because of the goalscoring skills of aguero, and the fact he is never inferior on just about anything
