Selling Malick Thiaw is a priority for Schalke according to reports in Germany, with sporting director Rouven Schroder admitting they have too many central defenders as things stand.
The towering 20-year-old was linked with a move to Celtic earlier in the window as Ange Postecoglou looks to further bolster his defensive ranks. The German side, meanwhile, had been close to landing Christopher Jullien from the Hoops - but settled on Japan defender Maya Yoshida after the deal collapsed.
It means the Bundesliga side now have six central defenders on their books and RUHR 24 say that moving one or two on is essential before they can make any more signings. They quote Schroder, who addressed Thiaw by name, and admitted it's "clear" there will be some players moving on in that position.
