A late Mats Hummels equaliser handed Borussia Dortmund the advantage against Shakhtar Donetsk ahead of next month's second leg as the German side secured a 2-2 draw in the Ukraine.
At a freezing Donbass Stadium, Dortmund enjoyed large spells of possession, Jakub Blaszczykowski and Hummels going close. It was the hosts, however, who went ahead, Darijo Srna's free-kick beating Roman Weidenfeller after half an hour. A fortunate bounce allowed Robert Lewandowski to equalise before the break, only for Douglas Costa to regain the lead.
A minute's silence was held before the match for the victims of a plane crash involving supporters in Donetsk, in which at least four people lost their lives.
