Greetings!
Just started up my first career in FM2023 with the following database that tracks down to lvl 11 in the English football pyramid: https://www.passion4fm.com/english-lower-leagues-database/
Six games in and Feckenham are undefeated, on top with 16pts. The hardest part has definitely been signing on staff who don't care about being at such a low-level team.
