I think the game versus France was a huge reminder to everyone that Italy is in the midst of a rebuild... and they have to rebuild fast.
The biggest trouble spot is clearly on forward. Luca Toni seems to be the only pure striker on the team, and not only is he presently hurt, he's 30.
Inzaghi is the most frustrating player I've ever seen. He's either really on, or really, really off. When he's really off, he makes everyone around him look bad. The guy is what, 34? He's pretty much done, at least at the international level.
Del Piero is not a runner. Why Donadoni plays him like that I'll never know. If he doesn't want to use Del Piero like Juventus does, as a support striker up high in the middle, then don't bother calling him up and making him look like crap. At 32, his last hurrah is likely Euro 2008 at the latest.
Lucarelli just blows. I dunno why people like him, he's just clumsy and not very good at leading a line. He seems to have to be the centre of attention for the rest of his team to be effective (as he was in Livorno), and that's not Italy's tactical MO. Stop calling this guy up, Donadoni. He's 31 and playing in an inferior league....
Di Natale isn't bad, but he's not international quality, and there isn't exactly room for him to improve, seeing as he turns 30 in October.
Iaquinta is actually, in my opinion, the best option for a Donadoni coached team. He's big, fast and strong, and can play wing or forward. But he's supporting cast, not a main event. At 27, he's one of the younger Italian options. There might be room for him to improve as he just entered his prime.
Quagliarella is one of those guys that Italy must prime up at once. He's arguably the best young striker at their disposal.
Gilardino was the great white hope, but he has stalled his development and at the moment is not the best option, though I'd call him up over Lucarelli or Inzaghi.
Di Michele didn't look good for Italy, despite his good performance for Udinese/Palermo. Bonazzoli is not a great option, and Rocchi, while not bad, is over 30 as well, and its time to look long term.
Miccoli and Rosina should be considered viable options for testing if Italy wants to be more than an also-ran at Euro 08.
For today's game... I'd start Quagliarella and Iaquinta, with Del Piero subbing in for one of them around the 65th minute.
