DORTMUND, Germany Borussia Dortmund could be without midfielder Raphael Guerreiro when they host Benfica in the second leg of their Champions League round of 16 on Wednesday, with the Portuguese nursing a muscle injury, coach Thomas Tuchel said on Tuesday.
The Bundesliga titans came back from a 1-0 deficit after the first leg to seal a 4-1 aggregate win, with Christian Pulisic joining Aubameyang on the scoresheet with his three.
"Tomorrow we have a floodlight game and it's all about scoring goals and going forward".
They also have history on their side having won all five previous home matches against Portuguese teams, including a 2-0 win over Porto at the same stage last season.
The two sides will play out the second leg at Dortmund's Signal Iduna Park on Wednesday, and Castro believes that his side are favourites to go through to the next round, albeit being the ones who have the harder job.
"Now we have to be aware not to concede a goal at home, because then it gets more hard". Borussia Dortmund despite the defeat in the first match, remains with good chances to go to the next round, because the Dortmund will certainly come to the field, exclusively for the victory. "However, we have seen how strong Benfica are as well and that they can score out of the blue".
But the bad news Dortmund were dreading was confirmed on Sunday - club captain Reus tore his hamstring in their 6-2 rout of Bayer Leverkusen on Saturday and is out until next month.
"Marco Reus was in a fine form", said the 29-year-old. "But there is no doubt he is a loss, he was in outstanding form".
Benfica meanwhile only have one major injury concern in Ljubomir Fejsa who is out.
He is on 28 goals for the season as Dortmund reached the last eight in Europe for the first time since 2013/14.
