If your strikers arent scoring then try buying very good AML/Rs, who tend to score more than strikers.
I've had seasons where my strikers cant score a goal to save their life and I end up changing up to 4 partnerships in a season. I found a remedy by playing AML/Rs who feed off assists from strikers. Also, if T11 form cycle remains predictable, then next season, they (your strikers) will be the league top scorers.
Also, some ST play better with a strike partner, some play better as a lone striker, some play better on the left, centre or right...
