It's illegal I think. I used the below a couple of days ago, beat a team two levels higher in the Cup:

-----------ST------------
---------------------------
ML---------MC--------MR
----DMC--DMC--DMC----
DL---------DC---------DR

Blue arrows on all 6 midfielders, very defensive, through the middle, own half, hard tackling, long passes, zonal marking, counter attacks, no offside traps.
