Borussia Dortmund will be without Mario Gotze for their Champions League last-16 tie against Benfica.
“He most recently had adductor problems,” head coach Thomas Tuchel said of Gotze at his pre-match media conference.
“He had one training session but unfortunately it is not enough for him to help us in this game.
“It will be a big task for us against a very proud club. I am really looking forward to it. Benfica can be very fluent in attack while staying compact in defence.
“I do not think there is a favourite and we cannot make comparisons to the group matches against Sporting. I trust us to put in a good performance – we have often done so in the Champions League.”
