This tactic gave me massive scoring figures, even as a massive underdog. You may get scored-on but you will almost certainly score more.
Be sure that you have at least some decent enough ball-playing defenders because that's where most of the plays will originate from.
Most of the goals are scored by the Poacher but both strikers score consistently.
I didn't mess around with specific player instructions and don't get much results from set-pieces so that's something that could use with some improving.
