Chris Schmoldt, the sporting director of MSV, stated that Hartwig is returning to a familiar environment to gain important match practice, and his development will be closely monitored. The proximity between Duisburg and Bochum ensures that they can easily keep track of his progress. Transfermarkt currently estimates his market value at 150k euros.
