Lol no. Marking has nothing to do with this. If you put aml/amr to the side attacking midfielder place (same as in previuos version aml with blue arrow) than he plays on the side. If you put aml/amr as side striker (aml with red arrow) than they "Cut mushrooms" and play in the middle. Don't know how he acts as a aml without arrow coz its hard to predict where exactly is that place in the box . I think that is because side strikers is not recognized by the code because there was no such a position in the previous version. Anyway that was discussed in the other posts.
