Borussia Dortmund chiefs Michael Zorc and Hans-Joachim Watzke have refused to rule out the prospect of the club signing new players before the end of the transfer window.
BVB's injury-hit campaign was dealt another blow at the weekend after it was confirmed Jakub Blaszczyskowski will be out for the rest of the season with a torn knee ligament.
Dortmund has been quiet thus far in the winter window but sporting director Zorc admitted Jurgen Klopp's side could welcome new faces prior to January 31 as they look to get their campaign back on track.
"I've never ruled anything out," he told Ruhr Nachrichten. "There are one or two aspects we are thinking of."
CEO Watzke revealed the club's officials have discussed potential transfer targets but warned they will not be rushed into making signings simply because of the club's latest injury problems.
"We have discussed internally and checked the market," Watzke said. "However, we will only do it if it makes sense financially and sportingly."
Ji Dong-Won, who is set to move to Signal Iduna Park in the summer, scored the equalizer for Augsburg at the weekend to snatch 2-2 draw with Dortmund.
