Schalke ace Leon Goretzka is interesting Southampton.
Bild says a scout from Southampton was in the stands during Schalke's final pre-season friendly against Twente Enschede on Sunday and Goretzka was his main focus.
After Morgan Schneiderlin's Manchester United exit, Southampton are in the market for another defensive midfielder.
Despite already securing a deal for Jordy Clasie, a move for Goretzka is also reportedly on the cards.
However, Southampton will have to stump up €16million (£11m) to sign the highly-rated German star.
