My question as general is "How to make sure that ST will shoot towards goal more often?"

I will explain - when I watch my games, the ST are far more likely to pass the ball Even when they are 1:1 with the GK, or worse many time they pass where no GK is in front of goal
For a few games I chose long passes, but nothing changed. So this season I sold all of my ST and after buying 4 new ones the problem is still there- my ST just do not score goals, THEY PASS THE BALL!!!!!!!! Three of them are 6 stars, and the other one is with 7 stars and "one-on-one ability", all under 25 years. My team has won most of the cups and cl's so far, but my MC are always involved in the goal and is REALLY annoying when facing hard opponents and you just watch this joke. My main formation- 3dc-2dr/dl-3mc-2st. I always give attacking bonus(at least 6%) and always play attacking mentality
