Thomas Tuchel and Rui Vitoria's teams are separated by just one goal going into the second leg of their Champions League last-16 clash in Germany
Borussia Dortmund host Benfica at Signal Iduna Park on Wednesday in one of the more finely poised Champions League last-16 matchups.
The Portuguese outfit were 1-0 victors in Lisbon a fortnight ago and will travel to Germany in the knowledge that a goal will put them in a strong position to qualify for the next round.
Dortmund have the attacking talent to blow teams away on their day, however, and will hope the speed and exuberance of their young squad outweighs their inexperience.
