But once again, focus on game you can win ! A prestigious WIN worth no more no less than a win against the weakest team !!!
Save enthusiasm and manage your game time as much as you can.... And try to remain in cup as long as possible, because in addition to money gain, its also a spot to increase the enthusiasm of your team.
