RB Salzburg have set a new deadline for Karim Adeyemi to be sold.
BILD says Borussia Dortmund are frontrunners to sign the 20-year-old, who has impressed for his club this season.
While earlier reports suggested Dortmund were closing in on a deal and agreed personal terms with the player, the situation 'keeps getting worse'.
The club are stuck in a 'transfer poker' for the German international and face a deadline of April 17 (Easter Sunday) to get a deal wrapped up. They are also yet to meet Salzburg's €45 million (£38million) asking price.
The article adds that Liverpool are among the clubs also interested in Adeyemi, as well as Barcelona and Bayern Munich and could make a move should Dortmund continue to stall.
