Was this made before the latest patch?
Decided to give it a try on a new game with Chesterfield (recently relegated from League One and have a pretty decent team for League 2) I did everything suggested in the first post (training, team talks, match prep etc) and used the tactic from the very first day I started the game.
Season wasn't too great, only just got into the playoffs finishing 7th.. lost in the League Cup first round, lost in the Johnstones paint trophy first round, also lost in the playoff semi finals.
We did ok in the FA Cup though, although we had pretty easy ties. We got to the 4th round, losing 3-1 to Man Utd.
Overall, everygame we had very few efforts on goal (always less than the opposition) and normally alot less possesion (which is not that important I know) Not sure if the tactic was made before the latest patch came out though.
One good thing though, the striker I played in the lefthand side of the 3 strikers, had an amazing season.. scoring 30 League goals & getting 11 assists at the end of the normal season. (He then scored 2 more goals in the extra playoff games, taking him to 32 League goals)
