The Tactic: http://www.fileconvoy.com/dfl.php?id=g520eef4dc258f1ca999654851d79e52a24ea97aac
I swear guys this tactic is OP, I did the same tactic last year and got great results, this year its even better, I manage Manchester United, After winning the league in the first season i backed it up with the League, CL, FA, and CapOneCup and Community Shield. The key to this tactic i think is to have very creative players in your squad who can pass and are technically sound, especially in the positions just behind the striker.
These are the instructions: http://imgur.com/avHD2qf
Obviously from there retaining possesion is key, hence "retain Possesion" and winning back possesion "get stuck in". Also if you add the Run at defence instruction with players like ronaldo in your side you'll find you get alot of dribbling goals.
Also make sure team shape is set to "fluid" to allow these guys to have the creative freedom they need to score you goals.

From there you can see each players role. Make sure you have backup tactics, my 424 tactic is when im chasing the game, my 433 wide tactic is when i need to change things up during games (ie; not playing well, surprise opp etc)
Set pieces and penalties etc are straight forward nothing special about them.
