Borussia Dortmund coach Nuri Sahin said he still felt the trust from his players but would talk to club bosses after Tuesday's shock 2-1 loss to Bologna in the Champions League that stretched their losing run to four games across all competitions.

The manager is taking the brunt of the criticism for a poor season but issues off the pitch are as significant as those on it

Bologna had never won a game in the Champions League before. Borussia Dortmund’s 2-1 loss to the Italian team on Tuesday could be the last for coach Nuri Sahin who has now overseen four straight defeats this year.

Borussia Dortmund coach Nuri Sahin failed to receive the full backing of managing director Lars Ricken on Tuesday after the 2-1 Champions League defeat at Bologna. The Germans took the lead in Italy but ended up with a fourth straight defeat in all competitions.

After Friday's 2-0 defeat to Eintracht Frankfurt - Dortmund's third in a row - managing director for sport Lars Ricken put Sahin under pressure to win Tuesday's Champions League game. And now that the game ended in defeat instead, Ricken has left it open whether Sahin will keep his job.

Nuri Sahin enjoyed a stellar career as a player at Borussia Dortmund, but his tenure as manager of the black and yellow has been mediocre at best. Friday's loss at Eintracht Frankfurt only emboldened fans of the German club to call for a change in leadership for the squad.
