For the Goalkeeper, when the opponent shoots, you can press the up or down button to choose the level of Hissatsu you want to use. For example if the opponent uses a Level 2 shoot, say, Reflect Buster, you may want to use either Sangoku's level 3 hissatsu Burai Hand or his Level 2 hissatsu Fence of Gaia~

just a random piece of advice :P
