Lisbon: Borussia Dortmund were left licking their wounds after wasting several chances in a frustrating 1-0 defeat at Benfica in their Champions League last 16, first leg clash on Tuesday. The Germans misfired throughout the game with their top scorer, Pierre-Emerick Aubameyang, the worst offender, as he missed two one-on-ones with goalkeeper Ederson and saw his penalty saved by the Brazilian just before the hour.
