Based on your form of the players of the first page there is not much to complain about. Lots of 7-8-9's. The game just trolls your from time to time. I had a team which was in the lead for 13 points and then my performance dropped from average 7,9 to 6,1 loosing all games and ending up third that season. The drop in form was for 6 of my players (MC/wingers/Str).

All you can do is try stuff around untill you find the right form. Switch your mc's around. Switch your strikers around. Do it during the match to see if they improve on the other side of the field. It helps sometimes. I use the same style as you and it helped me.
