One big reason for why Italians rarely succeed with us, is that they are brought up with Italian football and knows the pressure of playing for a team like Inter. The team whose ambitions have always outdone its performances. They know this. They have lived in that environment their entire lives, while foreigners just knows us as a team who hasn't won for many years.
Personally I don't give a crap where players are from. Most of our foreigners are Italians anyway. Lived here for ages. Meanwhile, the only Italian player that has become some sort of symbol for us in the last years has been Materazzi. A late bloomer whom up intil the World Cup was considered a risky player. Now at 34 years of age, he's brilliant.
We have another World Cup hero too, who's been an absolute flop. Not even I could have predicted that Grosso would be this mediocre and so fast be surpassed by Maxwell.
What seperates Materazzi with Grosso, is that during the last years Materazzi has grown to be an Inter fan. Grosso is obviously not, nor does he have to be. But this club seem to have difficulties finding Italian players that can show as much commitment to the team and the pitch as Materazzi does. Our foreigners however show more passion for this team, especially the South American ones. They weren't brought up with another Italian favourite team or even played for that team.
I wouldn't mind having more Italians in the team either, but they have to make sense. Surely a player like Samuel could be replaced this season by an Italian. But are we ready to pay a lot of money on a back-up defender just because he's Italian (and that would be Barzagli obviously)? Which Italian player can replace Figo? Which foreigners should be kicked out of the lineup just to make room for an Italian? Grosso has had his chance, but failed to Maxwell.
Considering we more or less have our starting eleven for next season, this transfer market would be ridiculously big just to sign a bunch of Italian back-ups. They cost way more, and in the last decade they haven't performed as good either. This might change with our Scudetto now, though.
