I wouldn't say no to him either, so long as he isn't brought in for his FAIR price (~15 million euros). If Palermo wants some of Juventus' trash then by all means let them go hog-wild, but I doubt that will be the case. If it happens, it'll be a cash-only deal.
Here's my issue with this transfer: if they spend big bucks on this guy, they're going to make this out to be some kind of superstar signing (see: Diego). This most certainly isn't the case. He's 21 and he's a building block. He's not going to help this team IMMEDIATELY, and Juventus is in need of IMMEDIATE help. If Pastore comes with a solid proven player like Aguero, then okay. However, if he's going to be THE player that they spend 30 million euros on and tell us that he's a gift for the fans, yawn...see you in 8th place next year.
