Dortmund have secured a much-needed three points with their 4-3 win over Mamelodi, but two key takeaways stand out from that result.

First, their defense continues to show vulnerability conceding goals even from attacks that shouldn’t pose a real threat.

Second, the job is far from finished. Dortmund still need to win their final group match against Ulsan, because if they fail to do so and Mamelodi manage a victory over Fluminense, Dortmund could drop out of the top two, with only a one-point gap currently separating them.
