Not even sure if it will work for the 1 striker version though. Out of experience it seems to work best with a 433 three striker version. then again you can try ofc.
You need:
LB + RB best to have 15+ long trows and the individual skill Long flat trow.
Then you make sure that your left trow ins are taken by the respected side. So LB takes all left and RB takes all the right ones.
Left side in tactics should look like this:
GK: Default
DR: Stay back
DC: Stay back
DC: Stay back
DL: Default
DM:Come short
MC:Come short
MC:Come short
ST

Right side:
GK: Default
DR: Default
DC: Stay back

DL: Stay back
DM:Come short

I havn't tried it yet because it's such an easy way to score its just out of balance. As soon as your defenders learn " Long flat trow" They are able to trow the ball as far as ****** Narnia. Every last 33% of the field will be treated as basically a corner. Then again it was made on a 433 so you might wanne tweak it a little. For example watch out that the Half back is not being dragged out of position to much so you are exposed.
