need help setting up a goal machine strikers

i've been playing with numerous tactics (with different save game).
some work like wonders, some just plain trash.
but in all of my game ( 4 of them), i found the difficulty to find a good setting for my strikers.
sure they score, but not as many as i have expected. 1 save game in particular is really disapointing ( 1 season, 27 matches played, 5 goals)
i have use diferent setting, AF/CF/DLF/T/P
i set creativity high/low/med.
long shot rare/often.
almost every setting i have used.

i need help the setting of a good goal machine strikers.

Well I would see if your midfield is creating enough chances as that might be the problem or that your wingers are not creative enough
