Actually there shouldn't be a definite tactic to counter another formation. Formation is probably just half of the battle. The other half is made up of players & random game engine. This is supposed to probably add to the realism. You can counter specific threats with the right formation, but sometimes you cant counter the whole opponent especially if some are on form.
Just read the suggestions and go with your gut. No such thing as a guaranteed winning counter esp if both managers are actively playing.
Good luck mate
