Barcelona were lucky to escape Germany with a point as they played out an entertaining goalless draw with Borussia Dortmund.
On a difficult night for Barcelona, Jordi Alba was forced off with a first-half hamstring injury, before Nélson Semedo conceded a penalty.
Marco Reus stepped up for Dortmund, only to see his penalty saved by the excellent Marc-Andre ter Stegen.
Barcelona pushed for a late winner and sent on both Lionel Messi and Ivan Rakitic, but neither side was able to break the deadlock.
The draw gives both sides one point from one match, with the Catalans set to host Inter Milan on Oct. 2 and the Germans visiting Slavia Prague that same day.
