The incident took place during a Bundesliga match. The ball went out of play, and when Bjelica reached for it, he refused to hand it over to Sane, who wanted to resume the game. Sane attempted to grab the ball from Bjelica, who then threw it behind him and verbally and physically confronted the Bayern forward. He pushed Sane in the face twice before teammates and coaching staff intervened to prevent further escalation.
Rafael Gereiro scored the only goal of the match just a few seconds into the second half. With this win, Bayern closed the gap to four points behind Bundesliga leaders Bayer Leverkusen, who have 48 points after 18 matches. Union Berlin currently sits in 15th place with just 14 points.
