If Marinovic is on the move, I'd say he'll be looking at Germany first. His girlfriend lives there, he knows the culture and speaks the language.
I also note his old club Unterhaching (them of the 'pub leagues') are 5th in Liga 3, so in with a chance of promotion to Bundesliga 2.
From an AWs perspective be good to have our no 1 keeper, playing in a league that recognises FIFA windows, ie not the MLS.
But I guess the most important thing is, that he goes to a club where there is a good chance he will be the starting keeper - which in short term will be tricky when most leagues are about halfway through their seasons.
