I have been playing with this tactic since I posted the last comment. I have changed the striker to a Deep Lying Forward (if my translation is correct). This has given me better results in offensive moments.
Besides that, I have changed nothing about the tactic. The pressure during defensive moments is very good, while your team won't get many cards. Great tactic!

PolterGijs - Sounds very good.

This tactic works quite well on my lower league saves. For instance I am getting Ijsselmeervogels from the Dutch 3rd Tier all the way to the highest level. Lost to Benfica with 3-0 or more with other tactics, this tactic gave me a 1-1 or a 2-1 loss most of the time. My Ijsselmeervogels team is rated lowest of all Dutch highest tier clubs, so this says something right?
