Well just done an 8 game quick test at work with my old pompey save and won 4 in the league drew 2, won 1 fa cup 3rd round game and then lost the 4th round game to leeds who are 2 leagues above us but we were the better team just didn't score, so yes I feel this could work in lower leagues as well.
OIs or not mate? Currently getting smacked by every team using Betis
