If I am busy and want to decrease number of matches, I can intentionally lost matches to avoid participation. However, I cannot do so for league and CL group stage.

I remember that there was old suggestion for allowing managers to opt to rest for some seasons and come back later. I always like this suggestion. Hope this is still being considering.

In addition, I will be even more pleasure if managers will be allowed to opt to participate the competitions in upcoming season. Then if I am very busy but still want to play some matches, I may opt not to play league, but still opt to participate Cup, CL, UEFA, etc.

Hope this idea is not super crazy.
