If it's going to cost us 20mln + Poli who's valued at let's say 5mln then why not just give them 25mln and they do whatever they want.
edit:
Di Marzio: "Poli is very close to Juve in a deal of 5 million + 50% of the talent Bouy. Then he'll be loaned to Fiorentina, a step to Jovetic"
Okay sending him on loan or co-own makes more sense. Now watch Bouy fuck up the deal.
