Some tactics (5-4-1, 4-5-1, 5-3-2) seem to be played only with "normal" attitude. Is there any way to change or unlock that and play those tactics with defensive or offensive attitudes too?

nope, i don't think so.

I know for a fact you can change the attitude to defence or attack in 5-3-2 on the PS2 version. I asked folks here a couple of weeks ago why you can in PS2, but not in PC version to no avail.

Thank u for the information. I really hope that there's some possibility to unlock these formations, it would add more tactics to the game.

in due time i suspect. when people get to understand the game a bit more.

I think it is possible, but I have to investigate more on the roster files.

It would really be a progress for the game, hercules.
