​Borussia Dortmund manager Thomas Tuchel has confirmed new signing Mario Gotze will miss the club's DFB-Pokal clash against Eintracht Trier on Monday, while Marco Reus' return from injury has been pushed back after a setback.





Gotze was absent in Dortmund's DFL-Supercup defeat to rivals Bayern Munich, but featured in Monday's 3-0 friendly win against Sandhausen.





Tuchel, however, is not prepared to draft Gotze back into his Dortmund side for the game against Eintracht after the Germany international injured his adductor in training.

"Mario Gotze has complained about a slight adductor problem after training on Sunday morning, which is best described as muscle tightness," Tuchel was quoted saying on ​Goal.





"As a precaution he will not play at Trier. He worked very hard over the last week. Christian Pulisic will take his place in the squad."





Tuchel also confirmed in his news conference that he does not have a return date for Reus, who was expected to start training again this month, after he suffered a setback.

"The first reintegration point we had envisaged passed a few days ago. Caution enjoys the highest priority," he said.





"Since we have not counted the days and obsessively pushed for deadlines, I am only able to say he will return when he does.





"If there is still a risk, we prefer to take a step to the side. We have, therefore, shifted his return back by a few days."





After using Roman Burki as first-choice goalkeeper for DFB-Pokal games last season, Tuchel has decided to give Roman Weidenfeller the role this time round.





"Roman Weidenfeller will be in goal for the DFB-Pokal games this season," the Dortmund boss confirmed.
