In the 34th minute of the match, when De De collided with Hannover 96's Czech forward Steiner and went down, everyone just thought it was a poor piece of defending.
After all, Steiner had beaten De De, crossed the ball from the right side of the penalty area to the front of the goal, and assisted Côte d'Ivoire forward Didier Ya Konan, who scored to give Hannover 96 the opening goal.
But as the Hannover 96 players celebrated their goal, Hummels and Subotic were desperately shouting for the referee and the team doctor. Up at the front of the pitch, this sent a chill down Wang Shuo's spine.
De De was on the ground, clutching his left leg with a look of agony on his face.
Klopp Syndrome!
'Is it happening again?'
Team doctor Dr. Marcus Braun quickly rushed onto the field from the sidelines with three assistants.
As a major club, Dortmund was equipped with one team doctor and three physical therapists.
