JP Woody's Liverpool tactic worked wonders for me, not sure where to find that though.
To be honest mate, try developing your own tactic to suit the players you have/buy. Its quite rewarding when your tactic pays off. But once you do use a new tactic, be it someone elses or your own, stick with it for a little while. It's highly unlikely it will work immediately, as the players will need time to adapt to it.
