Dortmund had taken the lead and appeared to be in control through Julian Brandt after 18 minutes, but the visitors pulled level just before half-time. Brandt struck again early in the second period, only for the away side to strike again with 15 minutes left. According to Schlotterbeck, complacency set in rapidly as he criticised the team's attitude after going 1-0 up, suggesting that individual egos took precedence over the collective game plan demanded by manager Kovac.
"After the 1-0, we started playing extremely sloppy and having incredibly bad first touches," Schlotterbeck said. "Everyone plays their own game a little bit. It is not bitter, it is actually really bad."
With the game in the balance, Kovac turned to his bench to inject fresh energy and secure the three points, with Karim Adeyemi and Serhou Guirassy coming on while they were 2-1 up, while Emre Can and Julian Ryerson were introduced immediately after the away team's second equaliser. However, Schlotterbeck felt the replacements had the opposite effect, offering a damning verdict on their contribution.
"The players who come on lose every ball," he stated bluntly. "If you come on in the 60th minute, I expect 30 minutes of full steam. We combined a bit right and left, chipping in front of the goalkeeper and wanting to make it look nice, but you have to kill the game and we didn't do that."
Schlotterbeck also questioned the work rate and focus of the squad during the final stages of the match.
"We play in the Champions League and that is way too little," he added.
