The 25-year-old has played just three games for the Magpies this season after struggling to break into the side’s strong defensive lineup.
With Scharenberg having family in South Australia, The Herald Sun are reporting that the Crows could be a potential suitor as the club looks to rebuild.
The Magpies will likely have to say goodbye to a number of experienced players, with Darcy Moore and Jordan De Goey set to demand a large sum of their salary as the pair remain without a contract for 2021.
Scharenberg is likely to be one of those players on the outer, while Tom Phillips’ name has been tossed up as gettable.
Scharenberg has played 41 games for the Magpies since being taken with the No.6 pick in the 2013 draft.
