Why don't you make it so that when the user holds down the mouse button the cross hair appears and starts to rotate, and everyone else on the pitch pauses whilst you choose, kinda like the game pausing, then once you let go of the mouse it passes in that direction?
Not quite a bad idea I guess, but if you pass all the time, plus wanting to have multiplayer, the game will be paused a lot. The speed will be out of it and that means most of the time the fun of the game.
