I started a save just to scout players to make a shortlist of who I wanna buy after the game came out, so I ignored friendlies and training = players lacking match sharpness. Just playing around to try random tactics. Got 3 consecutive draws and 2 losses. Then I tried your tactic in the next 2 games and I won lol With this Liverpool save that has a lot of injuries, and the fact that I changed tactic every match, it says a lot about how great your tactic is.
One question though - The game against West Brom ended 3-2, with 2 of their goals came from through passes, I had to drop the defensive line to slightly deeper and time wasting to hold out the win. If the opponent exploit the defensive line, does making the defensive line deeper has any effect on the tactic?
I think it does, because no midfielders are on a defensive duty you need that high defensive line to avoid a big gap being there. When i need to hold on to a lead i just put the mentality on contain and tell them to be more disciplined, you might also in that cause want to switch the dlp to defensive. It might work though to make the defensive line deeper, i have never tried it. If you try it let me know whether it works!
