Training your players right b4 a game does NOT help, it actually drains down their condition and they got less power and sometimes can't perform at their best.
Note:it does not help but if you manage to get about 5723 SP in a stretching, that would help.. if you get less than 5723 just don't train them.
And yet if you train your players b4 a game they may also get ingured, this would make things even worse
Usually people train their players when they only got 1 game/day- if you've got two games you shouldnt train them as they got troublems recovering for the next game.
