there are real rules of football, and then there are Nordeus rules of football. You cannot have 3 players lined up on either side of the pitch. so for example, you cannot have

-----------ST-ST--------------
-AML--------------------AMR-
-ML--------MC-----------MR-
------------------------------
-DL---------DC------------DR-

illegal according to Nordeus but not in real life.

-----------ST-ST--------------
-AML--------------------------
-ML--------MC-MC-MC---------
-------------------------------
-DL---------DC--DC------------

Also illegal according to Nordeus. reason: nobody on right side. you have to have at least one on each wing but not more than two.

Ask Nordeus why they set it up this way, but that is the way wingers work.
