Against the only other team in the league to have opened the season with three victories, Thomas Tuchel's squad was forced to settle for a point.
Bayer Leverkusen held 11-time reigning champion Bayern Munich to a 2-2 draw away on Friday thanks to an injury-time penalty from Exequiel Palacios, establishing itself as a title contender in the Bundesliga.
Dayot Upamecano scored with Bayern's final shot, but a video review determined the France defender was offside, and Thomas Tuchel's club was forced to settle for a point against the lone other team to have opened the season with three victories.
Leon Goretzka appeared to have given Bayern a late victory to keep the champion's unblemished start.In the 86th minute, substitute Mathys Tel crossed from the left and found Goretzka open in the centre to shoot what many believed to be the game-winning goal.We appeared to have struck it lucky, but the judgement ultimately went against us, according to Bayern coach Thomas Tuchel.
After Alphonso Davies fouled Jonas Hofmann, VAR assessed a penalty, and in the fourth minute of stoppage time, Palacios equalised the score.
Thomas Müller, a seasoned Bayern player, lamented the "very soft penalty." In England, it would not have been given out.
There was contact between Davies' leg and Hofmann's calf, according to referee Daniel Schlager, who supported his choice.
