The name shows the philosophy of my tactic!! The best defence is the possession of the ball!!
I used it in FM17 with PAOK (Greece) and I have managed to win Europa League against Real Madrid (in extra time) in 2021. However, I use it again in FM18 with very good results (except 1st year: finished 2nd in the league).
Use the control mentality in the most games, except these you are a big outsider!
Use flexible shape from the beginning, unless you want to hold the result against to a big opponent; in that case change it to structured.
Full backs: Stay wide. Go forward
Cenre backs: Short passes
Attacking Midfielder: Hold up ball ( change him to Second Striker if you are home, time passes and you can't score)
In 8/10 of matches you will achieve ball possession over 60% and over 12-20 shoots.
I hope I helped!
