A couple of people have queried how this the tactic set would work in LLM so, since I was playing at East Fife, I thought I'd throw my tuppence worth in.
It might be a simplistic view, but I wonder whether it's a simple case of 3-4-3 is terrific with big teams (see that chaps unbeaten run with Man Utd above) and the 4-4-2 / 4-4-1-1 is better with minnows, given it is less susceptible to be torn apart on the break if your average players cause the move to break down.
I tried 3-4-3 until half-time in my fourth league game of the season, having leaked a barrel-load of goals in every game. The 4-4-2 immediately turned around that game (winning 4-3) and I used it for the rest of the season, going onto win League 2 with a very, very average group of players and piecing together a phenomenal run of form towards the tail end of the season, where every game seemed to herald four goals (ignore the final two league games of the season - the league was won so I was giving fringe players a game to stop them from whining).
Additionally, the tactic dominated the average ratings, while my wide players were top of the assists chart. Given the amount of defensive work they get through, I also thought 15 league goals apiece was a pretty good haul for my strike pairing. (As a reference point for the screenshots below: Austin and McKinnon are my strikers, McAleer and *** are my MR and ML respectively, Phinn is MC and Walker is DMC.)
Huge thumbs up. Looking forward to seeing how it does in League 1. Will perhaps revisit 3-4-3 with a better team, but I would suggest the 4-4-2 is a real go-er in LLM, particularly after Christmas once it is fluid.
