Complete joke of a tactic. Can't be asked to give longer feedback . I will only say that this is the worst i played in every FM there was.
From what I see:
1) you don't rotate nearly enough, so I may guess you're conceding a lot late in the game;
2) your playmaker is consistently horrible, I'd try Brandt, Can, or Reus instead;
3) your defenders aren't performing well, which can be a stamina issue, especially for Sule (see #1). He scored twice, but his rating is too low (w/o scoring, probably around 6.4).
More insights can be given after seeing detailed stats, especially for defenders, but if you "can't be asked" that's probably all.
Also, your pre-season was quite... unique. What's the point of it? Your defenders didn't work at all, you hadn't a chance to detect any problems with your defense. No wonder it backfired when official matches started. I always play friendlies vs stronger opponents, so it's possible to fine-tune everything before it's too late. Probably, I need to write it explicitly in the manual.
I find FM24 much easier compared to FM23. It's like playing on "I'm Too Young to Die" after suffering "Ultra-Violence", mostly 'cause of too many defense errors - if you press an opposition hard, you'll score a lot. I'm now continuing the save from FM23, and I'm on the verge of dropping it. The results are unbearable for the 23th team in the rating list, it's probably a bad tatics.
