I think Oliveria is injured, and has stayed behind in Turin.
But as some of you - such as gray and Adrian - mentioned, it would be fantasic if Mr Lippi field Maresca.
He deserves a bit more playing time.
By the way, this is from Calcio Italia (or Football Italia as it was used to be called):
David Trezeguet “took a knock to the ankle” and is also in doubt for Tuesday’s European tie, while Alessandro Del Piero has been ruled out until November with a calf strain.
I didn't put the quation marks on, so maybe someone at Calcio Italia - one of our most reliable sources - also had the conspiracy in mind...
