By looks of it your owners are just tight, it might be that they just being cautious due to the quick rise through the leagues, if you dont get left behind in the fight to stay up then hopefully they will give you some cash in jan, sometimes clubs are cautious first season up if you arent a premier league regular.
If you dont get anything in jan but do stay up then the summer should defo bring a decent budget with the amount of money it looks like your going to make this season, atleast your running a tight ship financially (i always try to keep things healthy)
