Why the hell wouldn't we want him? With Kun gone I wont say no to quality.
I Don't want him mainly because I don't see him as a 25+ mill € improvement. We got Del Piero and Quagliarella at SS, we are only competing in Serie A and Coppa, so we really don't need him. We could in theory spend the money we 'saved' on 'Kun' or Rossi on a position where we really need upgrading like CB, LB, CM [I don't see Pirlo fit in] and LM/LW.
If Marotta continues the transfer-strategy from last year, where the targetted players looked to be players at their peak [or past it] at Top Serie A-level, then we won't improve enough. I'm not demanding WC-class players. Serie A is luckily for us not that strong anymore, so we only need players on CL-level.
If we can't get players who at CL-level then why not try rebuilding with youngsters instead of players like Martinez, Pepe, Motta, Matri, Toni, Pazienza, Pirlo and so on..
P.s. I like Pirlo, but not in a 4-4-2
