Personally I don't think Balotelli is good enough to justify the hassle he brings so I probably would turn him down. That's not too relevant to Osvaldo though. He may or may not be worth the bother and I'll trust Poch on that as he's worked with him before.
Balotelli is also an example of a player who kept being picked for Italy despite the fact he played over here and wasn't first choice at his club.
