Borussia Dortmund have confirmed Mike Tullberg will remain in interim charge for Wednesday's Champions League clash.

Tullberg, previously of the youth setup with BVB, oversaw a 2-2 draw with Werder Bremen at home on Saturday in his first game since Nuri Sahin was dismissed.

Lars Ricken, Dortmund's sporting director, revealed Tullberg will again be in charge when they host Shakhtar Donetsk in Europe, needing a win to keep them in the competition.

"Mike will also be on the bench on Wednesday," said Ricken. "That was actually already clear beforehand.

"But I told him that it was all about the Werder game first, because I wanted Mike Tullberg one hundred per cent - and that's what we got."

As for the performance itself against Werder, Serhou Guirassy's strike and a Marco Freidl own goal had Dortmund in charge, only for Leonardo Bittencourt and Marvin Ducksch to drag the visitors level.

Tullberg was still pleased with what he saw from his side, who are languishing in 11th place in the Bundesliga table.

"My task was to lead the team until Saturday. Now I have the task of leading it until Wednesday," Tullberg told a post-match press conference.

"The boys put everything out there. You cannot accuse them of anything. I am more positive after the game than negative. We played 70 minutes with 10 players but still got a point."

Erik ten Hag, Niko Kovac and Roger Schmidt are all reportedly linked to the Dortmund vacancy, though Ricken says the club will mull over their options before making a decision.

"We are taking the time we need. I think we are in an excellent position at the moment with Mike because he can get through to the players," Ricken said.

The message for Tullberg remains clear, too, as the stand-in boss acknowledged the need for results.

"It's always about helping the club," he added. "In the first few years, it was about developing players and winning games, but now it's about winning games and stabilising the team."
