Form also, has nothing to do with training. The only relation I 've noticed so far (and I do a lot of training

) is
- a player out of form (and low morale) has bigger % to get an injury in training than the others
- a player who got power-train one day, is "carrying his fatigue" later in the game, so it's more possible not to perform or to get an injury.
So, when I power-train a player, even if he doesn't injure during this, I 'm not using him in a match that day.
