AML/AMR/AMC - these positions score more than ST. ( In my opinion ).
Make my players score? There is no solution for that...
But these things could help you :

* Use more than one attacker in your formation.
* I prefer to use 4-2-3-1 and my aml,amr or amc always score in a game..( ST rarely )
* Use attacking mentality and maybe red arrows on AML-AMR.

You should post a picture about your team and formation, so we could help you better...
