Dortmund took the lead in the 71st minute through a goal that bore Mateo's fingerprints without appearing in his statistical record.
His movement had drawn two defenders out of position, creating the space for a teammate to receive possession in a dangerous area. The subsequent shot deflected off a defender and found its way into the net, but the goal's genesis lay in Mateo's intelligent positioning.
Augsburg equalized with eight minutes remaining, a scrappy goal that came from a corner kick and highlighted the unpredictable nature of football.
Despite Dortmund's dominance in the second half, despite their superior technique and tactical sophistication, they found themselves sharing the points with a team that had defended resolutely and taken their chances when they came.
