I just reckon he was split . Also the Italians put a shit tonne of pressure young kids to all declare for them if they have a choice ie. play for us or you have no future in Italian football . But with thier mediocrity now in European football , and the fact he wasn’t picked despite this , they probably eased up on him .Volpato is a bit of a mercenary - pledges allegiance to Italy - they don't qualify for WC so he reneges and pledges for Australia. Italy's loss our gain i suppose.
I know Christian Vieri for example came real close to declaring for us . Ultimately he probably made the right choice and had a mad career , but yea apparently it was a hard choice for him .
