Yeah, but mentionned the U21 team because its where I have seen him regurarly (scores respectable numbers, but quite frustrating still). I doubt people bother to see Cagliari much besides when we play them. He has potential (possible future bomber), and I think he would be quite good for Inter if they recall him now this January, rest of their strikers either suck (Crespo, Cruz), or are absolute headcases (Adriano, Balotelli). So he would come in handy for them.
But yeah, he defenitely has an inclination to miss sitters, even if he is becoming a decent and consistent goalscorer (6 goals so far).
