Borussia Dortmund beat FC Schalke 04 in the Revierderby behind closed doors 4-0 at the Westfalenstadion on Saturday without six injured players.

BVB coach Lucien Favre had to make do without team captain Marco Reus, defenders Dan-Axel Zagadou and Nico Schulz and, midfielders Axel Witsel, Emre Can and Gio Reyna.

“I hope that Reyna doesn’t have anything serious,” Favre said at the improvised post-match press conference. The 17-year-old U.S. American was in the initial starting line-up for Jadon Sancho, who started on the bench due to calf problems but picked up an injury during the warm-up.

The 62-year-old was more positive about the prospects of Can and Witsel, who picked up muscular injuries. “They still need a while but not too long.”

It looks less promising for centre-back Zagadou, however, the 20-year-old picked up a ligament injury as the training restarted, which will rule him out for the rest of the season. It is also unclear whether Reus will fully recover from a muscular injury he picked up during a cup match against Werder Bremen in February before the end of the compressed season schedule.

“Marco Reus may come back but we don’t know when because he’s yet to train with the team. Nico Schulz has re-injured himself and can’t do anything for two to three weeks. Thorgan Hazard (cramps), Mahmoud Dahoud and Thomas Delaney were subbed off without any injuries,” Favre said.

Dortmund will travel to sixth-place VfL Wolfsburg next Saturday.
