Barcelona are tracking VfB Stuttgart fullback Borna Sosa.

Sky Deutschland says Barca had scouts posted last Friday night to watch Sosa in action in VfB's defeat to Borussia Dortmund.

The 24 year-old's contract carries a €25m buyout clause.

Sosa is shining this season and his form has attracted the interest of Barca as they seek cover for Jordi Alba.

In addition to Barça, Inter Milan and Chelsea are also keeping tabs.
