360 degree spin is where your player treads on the ball and, obviously, does a 360 degree spin around it, taking the ball with him, a la Zinedine Zidane... You can't do it without a gamepad, cos you need a right analog stick...
you can do this with keyboard as easy as with gamepad
just assign right stick directions in controls to 4 following keys (eg. z, x, ,c, v)
then ingame just press these keys one after another and you have Zidane spin
