Hummels comes to Dortmund’s rescue
Darijo Srna put the Ukrainians, who are deep in a winter break and have not played competitively since the group stage, ahead with a sweetly-struck 31st-minute free-kick before the prolific Robert Lewandowski levelled 10 minutes later.
Douglas Costa restored the home team’s advantage in the 68th-minute before Hummels handed the Bundesliga outfit a second away goal with a header three minutes from the end.
