Three second-half goals between Borussia Dortmund and Augsburg have seen the two sides draw 2-2 at Signal Iduna Park in the Bundesliga.
It was actually a strong start from Augsburg, who were keeping the ball better than their hosts in the opening exchanges, but Dortmund took the lead much against the run of play.
After just six minutes, Marco Reus took the defence by surprise with a quick free kick and Bender was there at the far post to tap in and put his side ahead.
However, Augsburg continued to see more of the ball, but despite a couple of free kicks from Halil Altintop that were headed away, they were not threatening Roman Weidenfeller's goal.
Instead it was Dortmund who could have doubled their lead as Henrikh Mkhitaryan combined with Robert Lewandowski with some quick passing, but he shot wide once he was in the box.
Bender went from hero to villain for the hosts as he turned a cross into his own net for the equaliser, which gave Augsburg some momentum.
Despite this, there was a magic moment from Nuri Sahin, who curled in a free kick for 2-1, but Dortmund were again unable to hold on to the lead.
This time the advantage lasted just five minutes as Ji Dong-Won headed in a cross for a debut goal and a share of the spoils for Augsburg.
