FYI, my level 25 team have 10 pairs of matches separated by about 3 hours on same day in this season. That is, for all CL matches and the Cup matches after preliminary round. For all completed matches, my players can only recover 5% conditions between 2 matches. The schedule is crazy.
BTW, the average training process with normal sketching of my 35T level 17 Team is 16%. I believe most of the players are fast trainers. But it is right that I do not use green packs to power train them. I just train them naturally.
