Dortmund would have double there lead when Nico Schlotterbeck came close to a second goal in the 38th but his powerful shot narrowly missed the target. Pascal Gross did put the ball in the net from close range on the stroke of halftime but his effort was offside.
Dortmund backline for more than an hour, finally succeeded with a quick passing move as an off balance Haraldsson beat goalkeeper Gregor KobelHaraldsson is only the second Icelandic player to score in the Champions League knockout rounds.
“We saw two different halves. We had a good first half, deserved the goal, had chances to score again,” said Dortmund coach Niko Kovac. “The second half we had no control, we were far too passive, brought ourselves into trouble.
“We were only reacting and from Lille’s only chance we conceded an equaliser. We now expect a big fight in Lille but we have the expectation to advance.”
