It seems it's an important factor for Alex to join some league/country that's less hyped with football. I don't think it's a coincidence he picks Australia and now India, I'd say he's giving his best to promote football world-wide. Sure, family factor plays a huge role, but I'd say promotion of football is pretty much on the same level.
He will probably pick MLS or Japan as his last destination. Even if he ends his career at India I think he'd go live there.
That will change in case he returns to Juve with some managing role at the club. So he'd return to Italy.
