Though Dortmund fell behind after 31 seconds, the rest of the match was pretty much one-way traffic in the other direction: BVB registered more shots (24-5), possession (72 percent), corners (10-0) and completed passes (874-214) than FCA. Only six percent of the hosts' passes did not reach a team-mate, compared to 21 percent for the visitors. BVB converted their first shot in each half. Here are the match facts.
