It's true that Cassano bags assists on almost all of Pazzini's goals but I think thats more a case of Sampdoria being over-reliant on Cassano than Pazzini. I think Pazzini just needs a talented creative force slightly behind him to perform well, it's not like if Di Natale sends him through on goal he's gonna blast over just because it wasn't Cassano who passed to him. He's only played a few minutes for Italy and he's already scored, at the very least he should get another appearance
I'm yet to see him without Cassano. He would probably score, yes, but I think at least 50% less goals. Not because he sucks but because there's no player that has Cassano's vision and who can provide some of his passes.
Funny thing, 95% of Italian strikers are clumsy and can't even run with ball properly. Borriello, Pazzini, Toni, Acquafresca and probably a few others. Rossi can, though...and now Amauri too.
So both Cassano-Amauri would have to play in my team.
