he has quality for sure, but he had major injuries in the past + he's not a goal machine which Juve need at the moment. he scored 27 in 101 matches for Fiorentina. Average player like Matri scored 20 in 46.
Again, he's a good player but Juve need another finisher around him.
that can make them serious contender for champions league.
why not both? they can raise good cash from selling Krasic, (Quagliarella or Matri) and the likes of Melo, Iaquinta, Motta and other flops which they loan every year.
Btw, I feel sorry for Elia. He joined Juve in hope of succssfull year and possible impact at euro. He played few matches, missed euro, and wasted one of his best years. That transfer was very Real like transfer.
