It takes a special kind of calmness to lob a ball from the edge of the center circle with enough accuracy to find the back of the net. Unfortunately, Christoph Kramer so calmly played this pass because he expected it to find his own keeper, not sail over his teammate's head and into the goal.
Kramer's mistake was the only goal in the Borussia Dortmund-Borussia Monchengladbach derby. Sorry, Chris. It's looking like your legacy is shaping up to be one big lowlight reel.
