Schalke are interested in signing BSC Young Boys defender Kevin Mbabu, according to Bild.
The Bundesliga club have already offered €9 million plus future incentives for the Switzerland international with Young Boys holding out for a fee closer to €13.3m.
With funds limited at Schalke, sporting director Christian Heidel will allow Franco Di Santo and Johannes Geis to leave the Bundesliga club.
A six-month loan deal with a purchase to buy in the summer could be a possible outcome for Mbabu, per Bild.
