Why? He's scoring goals regularly this season.
With five forwards in a squad, I'd always have one genuine poacher in there to provide a different option.
Pazzini is injured, so it's really down to Matri v Gilardino for that spot.
Given that Gilardino has played more and been more consistent this season, it's not unreasonable for him to be in there.
I'd consider it more of a joke that a shithead like Osvaldo, who has lost his place in the Roma team, is getting a call up.
