Haven't said that he's low lvl, im manager lvl22=oldschool 1 (playing with 2nd club lvl 10), he's oldschool 2.
I think that on higher lvls clubs have good finances so you don't need to buy and sell FA, but on lower lvls if you want to have strong squad with talented players, unless you loan money from bank, you'll need financial help through FA + cup and CL bonuses. I went through that, but used only few FA per season, not that much.
