Krasić has a good shot, same for Melo. Diego is arguably good, but we only saw that for Werder so far. I'm not worried about Giovinco's accuracy, but power. Marchisio still needs to learn. All depends on whether they can get in the same position like Camoranesi did against Samp in the 5-1 this season.
I have to admit, Candreva would be a good player to have for that system in terms of being able to pull off a shot.
