How does fm2022 change the rules of substitution in the Champions League?

First add the national rules, then find the replacement rules to be changed in the Champions League, find the replacement rules of the lineup, and modify whatever you want. This will use a patch, either by yourself or by others, which needs to be downloaded. Substitution is a major tactical adjustment both in the real football world and FM. Whether watching the above shots depends more on the 3D game engine to decide the outcome, or just watching the key shots or 2D depends on the traditional numerical engine, the substitution of players, like the change of game mentality, is an on-the-spot operation at the winning or losing level.
