The UEFA rules are that you must (this season) have 2 home grown players, e.g. players who spent at least two FULL seasons at Inter (or owned by inter? Going on loan might not count) before they turned 20, and 4 Country grown players (e.g. players born in this country and spent 2 years at a football club in this country before they turned 20).
So, as far as the list is concerned
HG: Orlandoni, Esposito, Bolzoni
CG: Materazzi, Toldo
So we have met the minimium requirements.... Could have technically dropped Orlandoni for Adriano but do you really want 2 keepers 5 and strikers versus 3 keepers and 4 strikers?
