Borussia Dortmund announced this Wednesday the dismissal of Nuri Sahin as head coach following a string of four consecutive defeats, the latest being a Champions League loss to Bologna.  

"Borussia Dortmund and Nuri Sahin will part ways effective immediately. The BVB has relieved its coach following the disappointing 1-2 UEFA Champions League defeat against FC Bologna on Tuesday night," the club stated in an official announcement.  

Dortmund’s sporting director, Lars Ricken, acknowledged the respect and appreciation for Sahin's efforts, their initial desire to collaborate with him, and the hope they had until recently of turning the team’s performance around.  

"However, after four consecutive losses, with only one win in the last nine matches, and currently sitting 10th in the Bundesliga table, we have unfortunately lost confidence in achieving our sporting goals together. This decision is painful but became unavoidable after the game in Bologna," Ricken explained.  

Sahin also shared his thoughts, stating, "Unfortunately, we haven’t been able to meet Borussia Dortmund’s sporting ambitions at this stage of the season. I wish this very special club all the best moving forward."  

Additionally, Borussia Dortmund announced that Mike Tullberg will take charge on the bench as head coach next Saturday in the Bundesliga match against SV Werder Bremen.
