Need an advice please :/

Well, as Cracicot said and as I mentioned before, I have no AML-AMC-AMR neither DML-DMC-DMR and it isn't an illegal formation because I have a DR and he covers the right side. One the left side however, I will have 2 players covering the side so that's pretty much the problem, that the formation is not symmetrical. Do I lose any possession by the way?

No, as long as you have a legal formation, you can play an asymmetrical formation without penalty.

Sorry, as long as you have 3 midfield players of any type, 1 striker, 3 defense of any type and one player on the left wing and one on the right, you are ok according to the research done on illegal formations.

all that to say, as long as you have your DR and DL, you are ok.
