Marco Reus marked his return from six weeks out in style, before Pierre-Emerick Aubameyang got his 26th Bundesliga goal of the season.
Pierre-Emerick Aubameyang ensured 2016-17 will go down as his most prolific league season to date with the final goal in Borussia Dortmund's 3-1 victory over Eintracht Frankfurt on Saturday.
Aubameyang passed up a pair of decent second-half chances before finishing a swift counter-attack to take his tally for the Bundesliga season to 26, improving on last-term's 25-goal haul.
The Gabon international's strike provided the gloss to a result that saw Dortmund recover from successive defeats to league leaders Bayern Munich and Monaco, the latter postponed by a day after an attack on the German side's team bus on Tuesday that hospitalised Marc Bartra.
