I know, that's the wrong thread, but I wanna tell you the result, because of your help:

Finally he started with a high defenisve formation: 4-2n-1-2w-1
I used: 3w-5-2V
attacking-down both flanks-short-on; low-low-man to man-on
I know, what you think... wtf? counter and offside on? yes, and it worked!!!

At halftime, we were leading 3:0, shots on target: 7:0. After halftime, he made a sub, changed formation to 4-1-1-2w-2. I went back to 4-5-1V, defensive. I missed, to turn off offside, so I conceeded one goal. At this time SoT were 7:3. After turning off offside, there was nothing more. Finally SoT were 10:3.

Maybe it helps someone.
