I'm using this tactic with Trastevere in italian Serie D (4th level). I have good results for a team that is predicted at the middle of the table but not amazing like other users.
Strikers score only occasionally and, more generally, I find very difficult to score more than 1 o 2 goals per match. All the six midfieleders got very average ratings (about 6,5). I have always 60% of possession but very few occasions.
I must say that I lost only one match out of 13 but I'm not killing the game like in some experience that I read here.
I don't know if it's a tactic that need more valuable players but I see excellent results also in Vanarama, and the level is very close to Serie D.
