Who wouldn't.
But to look at him doesn't mean you can get him. It's not as if Innsbruck isn't happy to get those kind of players (see Wachter and Kromp), but it's neither a given their club parts with them nor the players want to come to Innsbruck (see Dario Winkler who preferred Vienna and it's not hard to see why).
I don't think Salzburg would hold him with too tight a grip. Despite his junior national team pedigree, he's probably fallen to the bottom of the list of 98s, and has spent half the season with the farmteam. Of course, they would still have to pay...
Interesting you mention that. I have actually found that it is true that many players don't wish to go back and play in their hometowns. Many have a lot of negative sentiments associated with it. However, I think most farmteam players would eventually be willing to go to a place like Innsbruck. There used to be this mentality that went around that I thought was extremely destructive that "I don't want to play on a team that loses all the time", or something like that. But the players have observed how well their compatriots are doing on loan programs, and have become more open to the idea. I think if Innsbruck went to SBG's or KAC's farmteam and asked around, they could get a decent player or two.
