I used to have a lot of problems with strikers scoring in the beginning but I'm not gonna lie I have had some decent ones in these last seasons. My main striker Mayer was a 69T scout with Penalty SA and he is pretty amazing. Has an average 0.8 scoring ratio. Investing in a scout or recommended ST is actually a great idea. I suggest you usually play with 1 only, if you have an AMC it can help the ST a lot. 80% of my goals came from these two last season.
