my main ST (from recommend) for the last three season....
first season (LV7)...horrible....not scoring at all...
season season (LV8).... he is very good...score a lot...
last season (LV9) ...he is good at CUP (12 score and 9 assist), and CL....but in league....really bad...
this season, so far....seem, he can't play ST position (he is ST/AMR).... when all my team rating over 7.8....he is the only one rating 6.4 =.=!! i saw 3 times.... and even in the friendly game...also the same....i put him to AMR....well... rating rise.... but still.... not scoring....

i think that maybe happen due to the new training system....his positioning now is only 84%.....so....i think that make him can't score at ST.... (my other ST... positioning 105%....score almost every time i sub him in... and he only play ST...)

so...i think that only depend on the ST and the skill~
