Hello @DomLOL
I'm not seeing anything in your club vision about your board wanting to use youth players.
As I've explained previously if you don't have the option to upgrade youth facilities it's not a bug, your board just aren't interested at the time. If you want to circumvent that you'd need to the use the In-Game Editor but that is disabled on your current save.
For your German striker, he's just not currently interested in becoming a Gibraltar national, he's a pretty good player and probably feels he has a chance of a call up to the German squad at some point.
