Barcelona are shopping in Germany for a new centre-half this summer.

Barca are lining up a new defensive signing in the event they lose unsettled France international Samuel Umtiti.

Sport says Schalke defender Thilo Kehrer, 21, is on the radar, along with long-term Barca target Dayot Upamecano, of RB Leipzig.

Schalke have put Kehrer up for sale at a price of €35m after new contract talks recently fell through.

Kehrer is tied to S04 until 2019.
