Okay First things first in the game you need to get an agent that will allow u too actually enter the place/area where u can train your character its the collisium that let u perform drills and gain points to use on your states depending on how will u do.
Steps ============================================================ One: First what you need to do is skip all days up until the game day but dont go into the football match yet but also make sure that u ddidnt do the training yet that same week
Two: Go to the collisium and train your character in which ever area u want then go back to the calender and click on the game but dont play it yet. Just make sure a box comes up asking you weather u want to start the game or not it should be a small box if u reach the screen with the two controllers and the two teams u went too far.
Third: this is the easiest step press "B" or triangle what ever game system your using back out of it and go back to the collisium you should be able to train your states again you can repeate this as amny times as you wish or as needed.
