I've implemented this tactic myself, but mirrored. So the CWB is for example on the right side and so on. When it works, it's a really good tactic that provides lots of scoring and a tight defense. But the high defensive line naturally also caused me some goals, where the opponent's striker simply outran my defenders. But also I have the feeling you really need a Haaland type of striker to be really successful. Many times, my strikers miss plenty of 1vs1s or headers and end up with a 6.3 rating or worse. My team also bunches up in the middle and they can't really figure out a way to unlock tight defenses.
What I tried from the other thread that linked here, was to remove the team instruction of shorter passing, giving it to most players as a player instruction instead. I also told most players to shoot less, in the hope of creating more quality chances. But the results haven't really changed so far. I'm playing the Console Edition, so once my team's morale tanks, it's hard to get it back up again. I have a bad run of results and I'm afraid I'll be sacked soon in my second season. But I don't blame your tactics. As I said, when it works, it's really good football.
