Noone in the top half of League of Champions fields players that are below training cap. You need players over the cap there.
Excellent points in here @jelly13 . I used to be one that failed with extra training in the middle of a season. What i still do not get is what the training cap of certain players is - you mean try training (before submit) and when it is red or now green cap reached? But how can players be "over the cap"?
