Former Chelsea boss Roberto Di Matteo is emerging as Schalke's top managerial target.
Schalke are seeking to replace interim coach Jens Keller, who could be dumped sometime this month if results do not improve.
Sport1 says Di Matteo features high on Schalke's list of candidates ahead of Fulham boss Martin Jol and Greuther Fürth coach Mike Buskens.
