Ok, now seriously, thats a simulator, and 1st are under all, the players, and their internal skills. time ago we had rules, about illegal formations. Now do not exist.
I always defended that have to exist to at least have acceptable formations to face, same with the players under the field, we should see always 11 under the field not 4-5 like when contracts are not expired and teams are abandoned.
Game need some little changes, hope in some time will consideer some changes about that.
