Sinoy, Inzaghi has 10 goals this season, 5 of them from the last 3 match day's. He is in deadly form atm, but he should be way down the list.
Jec1, yes, because he is still talented.
Also, in Donadoni's useless formation, its best to play a big target man. Toni and Boriello should be those 2 players.
As for Del Piero, 18 league goals this season says it all really. However, Donadoni and his shit formation doesn't suit him. Di Natale is inferior to Del Piero on just about everything except for speed, and even than, he is hardly that fast.
Lippi's WC formation is the best and should have never been changed.
Gattuso Pirlo De Rossi
Cassano/Di Natale
Toni Del Piero
Montolivo in for De Rossi if we need a goal, Camo in for Gattuso if we want to hold possession (although based on the amount of tracking back/tackling Camo does, starting him isn't such a bad idea, but Gattuso is such a unique talent and thorn for the opposition that he must start), Di Natale or Cassano to start, Quagliarella for Del Piero, Borriello for Toni.
