Losing a mainstay player (Guirassy) certainly makes Stuttgart experience a decline in performance and it is natural that Stuttgart has to lose points even though there are new players like Demirovic but he needs time to adapt and certainly will not be like Guirassy. 3-1 is a humiliating defeat for Stuttgart and must evaluate what mistakes occurred in the defense and attack line which still looks very weak.
Indeed, Serhou Guirassy in Stuttgart last season was extraordinary, he even made history in the club as the top scorer in Stuttgart. And now, the club's forward really lost a strong figure in front. It will be quite difficult for Stuttgart to be as sharp as before with the current club combination. Even though they had been ahead since the 2nd minute, they were unable to optimize the various opportunities that existed. In fact, the opponent's counter attack was difficult for Stuttgart to withstand. The front line was not as accurate as before, and the back line had a pretty bad defense.

This stat tells everything.
Stuttgart had more ball positions, but the number of attacks, on the contrary, was far less than Freiburg who only had very few chances.
