Borussia Mönchengladbach's management criticized defender Ko Itakura for a red card that contributed to the team's defeat against Hamburg on Friday.
The dismissal, described as "bitter" by club officials, left Gladbach a man down and ultimately led to a loss in the match.
Itakura's sending off came at a crucial moment, and the club's bosses expressed frustration over the decision that they believe cost the team points.
