In the match for the German Cup against the Dresden club, Borussia Dortmund coach Jurgen Klopp almost collapsed from fear.
The strategist's heart sank when he saw forward Marco Reus suffer an injury in the 20th minute.
"I looked angry because it seemed to me that the opponent broke his leg," said the coach after the match, who was forced to make a substitution at the beginning of the match.
Although the severity of the injury will ultimately be determined on Wednesday, according to the specialist, it could only be a bruise.
"If it's just a bruise, then this evening wasn't bad."
The 2-0 victory extended Borussia's successful streak in Germany to 5 wins.
However, soon the Dortmund club will face a tougher opponent in the UEFA Champions League quarterfinals - the Turin team of Juventus, who bring a one-goal advantage.
