Barcelona have opened talks with Bayer Leverkusen for Jonathan Tah.
Fichajes.com says Barca have contacted Bayer about a price for Tah and been referred to his €25m buyout clause.
No immediate move is planned, with any bid dependent on the form of Yerry Mina.
Should Mina struggle to find his feet this season, then Barca will move to meet Tah's buyout clause.
Tah, 21, is also being tracked by Borussia Dortmund and several Premier League clubs.
