Palermo don't play like Barca, but who does?
From what I've seen Pastore likes the middle but drifts left and in. Unlike a Riquelme he does not need the whole game to get going nor does he need the whole 'system' to work around him. Although not a scorer and not as fast, he is similar to Kaka in that he can come and influence games without much fuss.
He can hold the ball up, ghost past defenders, has a killer final pass. However his awareness and movement off the ball to make space for himself and others is genius. If Hleb is the poor mans Kaka, Pastore is the thinking mans Kaka. Iniesta, Xavi and Messi especially are going to love him.
Messi and Pastore are close friends and Pastore has already rejected Madrid because of a 'promise' his made with Leo. However Palermo know what they have. He is going to take about 25M-30M to prise him away.
