Hello SpieleBambi! Are you pressing the A button when the ball is touching your character? The marked spot indicates where the ball is going to land so you'll want to stand in front of it. Then, when the ball is touching your character, press the A button to pass.
You could try a couple of matches on Easy difficulty in Quickplay mode to try and get the hang of the timing.
Let me know if this helps and thanks for playing Vollemental! :)
