perfect tactics by dv8r? I don't think that's better than the "How to win against any formation for dummies". In the beginning dv8r had to ask for help from adel, so basically dv8r learned from adel.
In theory as far as tactics in this game or any other football game is concerned, there is no such thing as a Perfect Tactic that will win you every game with any rubbish team, The only Perfect Tactics there is... is Perfect Tactics.
