They'll expand as your club grows in stature and finance. In lower divisions they don't feel it's necessary. for example, if you're a lower league club theres no need to send people to africa, because non EU players will only gain work permits if they play a certain number of international games, or if you're chelsea/arsenal/man u and the arse bandit FA bow down to your every whim.
I manage coventry, and it won't let me out further than europe in the championship. Not until they get promoted.
ahhaha i know how that feels, i took gambles on some players, spent my whole budget of 1.5mil on a brazilian centreback, relyinf on reputation of dubbed next lucio and turned out to be quite good
