Stuttgart fielded two different starting line-ups against the fifth-tier Hollenbach, with the former Central Coast Mariners star entering the match as part of the second half starting XI.
It took the 19 year-old rising star barely half an hour to show why he was regarded among the most exciting and clinical finishes in the A-League last season, showing poise and calmness to guide the ball into the net to give his side a 7-1 lead just after the hour mark.
Watch Kuol's goal here:
Stuttgart, minus three of its Euro 2020 stars, scored three more in what amounted to little more than a training run, but for Kuol - who joined the Bundesliga club on a five-year deal in Arpil, it was an important first impression.
"The bond between the two parts of the team was good and there was a certain amount of joy in the game, which also meant we scored many beautiful goals," Stuttgart manager Pellegrini Matarazzo said."
