nah for me it's a bit difficult to modify your formation, coz you only have players with limited position...

maybe, you can try this formation if you want:

.......ST↓.......ST..........ST↓....


.....Blaha↑....Coloci↓.....MC↑.....


DL.......DC↓.........Kehl↓.......DR

counter attack, own half, through the middle, attacking mentality, mixed pass, normal tackling..

basically, i dont like formation with 3 ST...

Good luck!
