Borussia Dortmund star Marco Reus’ first half injury in the club’s 3-0 victory over Wolfsburg yesterday soured Dortmund’s happiness at the victory, a report from Italian media outlet FcInterNews details.

The report highlights how the 30-year-old German forward was substituted off after only 28 minutes in yesterday’s game, providing a cause for concern for the Bundesliga side, who know the importance of next week’s Champions League clash against the Nerazzurri.

Dortmund coach Lucien Favre’s words to gathered reporters in a press conference yesterday displayed the club’s worries, saying: “He was hit, we don’t know exactly what the injury is.”

The club’s sporting director Michael Zorc discussed Reus’ importance to Dortmund’s upcoming two games, saying: “Let’s hope it’s not a big deal. BVB fans are looking forward to the crucial challenges against Inter and Bayern Munich.”

Reus has been strong for Dortmund this season, scoring six goals and providing one assist in his first 14 games of the season.
