Sevilla 1-0 Borussia Dortmund
Borussia Dortmund haven't kept a clean sheet in any of their last nine away games in the knockout stages of the Champions League, with their last one coming back in April 2013 v Malaga (0-0).
Two shots, two goals in our games tonight. There's been no action outside the goals.
