I have used this tactic for a season with both Crewe & Stoke, and had a prolonged campaign with Liverpool. I always attempt to create my own tactic in the football manager series, yet i must say this is by far the most successful i have been.
I first came across the tactic with Liverpool when just messing around with the game and came across instant results. It creates many chances but is also very solid defensively.
However, i quickly discovered that, due to its narrow nature, that away from home the opposition were creating a lot of chances and generally dominating the game. So i tweaked the formation a little and all of sudden my away form became better than at home!
Anyway.. On to the tactic. At home it uses 2 DM's, with a single central midfielder. Then there are 2 AMC's and a lone striker. It uses a slow tempo, with short passing. The only thing i would suggest is to ensure that the DM's are good at keeping the ball as they see the majority of the possession.
Away from home, the team instructions and mentality is similar. However the AMC's are replaced by wingers in order to help the more attacking opposition. I would recommend using this style at home in the Europe against the more offensive teams.
I got Stoke and Crewe promoted in the first season. Crewe as champions and Stoke in 2nd place. With Liverpool, my current game, i have won 2 premierships in the first two seasons, 1 FA cup and a Champions League.
I will try and get some screenshots up as quick as possible, but my laptop isnt having any of it at the moment.
For now though, try the tactic out for yourself and report the results back to me please.
