Pazzini can finish. But he's a classic poacher and nothing else.
It's the main point. Top club don't use those with a reason. Why would someone buy limited player, like Pazzini, when there are much complete strikers out there, who can create chances themselves and finish it off. I'll not go into it, but for an example, I'm thinking of a player like Benzema, Dzeko or someone.
Nobody wants limited strikers but Italians. Nobody.
If there's a one on one opportunity, what would Pazzini do? Nothing. He would be waiting for the ball right there in the box of course. It's what Gilardino, Pazzini and co. do
