Dortmund made two changes at halftime and the impact was immediate, with a high tempo opening to the second half. Christian Pulisic unsettled the visitors with his runs and fellow substitute Nuri Sahin instigated a wonderful team move that ended with Ousmane Dembele scoring.

Sahin surged forward before working the ball out to the left flank. Raphael Guerreiro then crossed to Pierre-Emerick Aubameyang, who knocked the ball forward for Shinji Kagawa to square to Dembele to tap into the net.

There was another moment of misfortune in the Dortmund defense in the 79th when Lukasz Piszczek's sloppy back pass to Sokratis Papastathopoulos was intercepted by Mbappe who knocked in his 19th goal of the season.

Dortmund responded within five minutes, with Sahin whipping the ball into the penalty area and Kagawa turning Jemerson before slotting into the net.

The game took place amid heightened security after a review of the policing operation by authorities in Germany and Spain at all three Champions League games on Wednesday. In Munich, Bayern lost 2-1 to Real Madrid while in the Spanish capital Atletico Madrid beat English champion Leicester 1-0.

Three explosions went off near the bus carrying Dortmund's team to the stadium on Tuesday just after it left a hotel, blowing in a window at the back and shards of glass struck Bartra.

After an operation, Bartra on Wednesday posted a photo of himself online with a bandage wrapped around much of his right arm, and a smaller bandage around his left wrist. The center back made a thumbs-up gesture with his left hand and wrote on Instagram that he's "doing much better."Dortmund said Bartra won't be able to play for several weeks.
