Andre Schurrle hopes that Dortmund's "Borussia" will show their strength in the second leg of the Champions League quarter-final.
Yesterday, Thomas Tuchel's disciples suffered a 0-1 defeat to Lisbon's "Benfica" team in the away match.
"I think we played better today, especially in the first half, when we created some good chances to score," said the German.
"Furthermore, we had the opportunity to score a penalty and could have won it.
In the second leg, we will show that we are better overall and deserving of reaching the quarter-finals.
"Today things didn't go our way and sometimes that happens."
The second leg of the matches will take place on March 8.
