I've reported it too, because since match concerned, my training sessions have been klartzed.
The number next to the training option on the side menu doesn't decrease with the training sessions you do, so the Preparation rating doesn't move from 'Good' and the pop up says the players still need x training sessions, even though you have done at least x sessions...
Upshot is, the team plays crap and you lose 0-3 to a -12%Q team.
EDIT: Although, since then they've played two more -10+% teams, played so-so and won 5-2 and 5-0... Does the Preparation rating even work?
