Hapoel will probably win in the return-leg in Bosnia as well. They just have way too much quality over this Bosnian team.
My suggestion, fade all Southern European teams (Bosnia, Croatia, Serbia) as they are all a bunch of scrubs.
Just look at Dinamo Zagreb, losing 0-1 at home to Koper?
Be careful. Traditionally Bosnian teams travel woefully but are solid at home. Plus at 5-0, Hapoel have nothing to play for and could send out the kids.
