If you think you have a national team caliber player you can send the NT-manager a bb-mail with his stats.
If you click on "Canada" on the long menu it will take you to a world map with a drop down menu, scroll until you get to "Italia." The country page has a link to the national team page.
That said, Pietro Frittelli chances of making the Italian national team are probably somewhere around 0%. Italy is the best team in the world and all-star potential isn't going to cut it. He's also 22 and only at 15k salary. To put that in perspective, the lowest salary big man currently on the Italian NT is 23, has a $127k a week salary and has superstar potential. The salary of their three centres are between $350k and $414k. The U21 centres are all younger than Frittelli and have between $79k and $185k.
