Can someone please explain what the indicators mean when you go to the 'Change Player' menu during or before a game. I am trying to figure out which players are tired. I don't have a manual for the game, so I can't find it there... I would like to know what the arrows beside the players names in red, yellow and green mean. What does the direction the arrow is pointing in mean? Also, there is a green bar.. is this a fitness/tiredness indicator?
