First game with this tactic, my team Leeds (6th place) lost 1-0 against Blackpool (18th place).
Will keep testing..
Next game, Leeds (6th place) lost 3-0 to Milwall (17th place) !!!!!
So...I don't want to test it anymore. If in 2 games against the weakest teams in the league, my team with your tactic lost both, conceded 4 goals and didn't score, then it means for me this tactic is weak.
Sorry..
Maybe give it a couple of more games, remember that the players have to adapt to the tactic aswell. I am testing this now with Liverpool. No transfer has been made. First match against Fulham home ended 1-0. Suarez the scorer. 7-1 shoots on goal. Will play some more matches to see, and will inform you guys then.
