I am stupid that I don't understand how it works through this picture. I am especially wonder if "Quick Training" is different from the existing "Personal Trainer" (uses tokens to improve quality, as I undetrstand). If it requires green packs instead of tokens for developing players, will it be possible players injured midway? Will the training be stopped? Will only part of the green packs be used? Or players are guaranteed to be injured for once and the training must be completed?
