#4 Fatigued Dortmund; Freiburg relentless
There were plenty of cases last season when Dortmund merely held their opponents for large chunks of the game to really turn it up past the 70-minute mark and roll them over. This usually also featured a cameo from Paco Alcacer who built a great goals-to-minutes ratio on the back of these performances off the bench.
Against Freiburg, not for the first time this season, Dortmund appeared to be unable to switch into a higher gear and put the game past their opponents despite leading twice. They have lacked ruthlessness in the past as well, but they rarely ceded control, but they're letting their opponents back into the game far too often now.
Their tendency to boot the ball out of the back in the final minutes is what handed Freiburg the impetus to keep going at them with some dangerous balls into the box, and they only needed to succeed on one occasion to make them pay.
