Barcelona are watching Erling Haaland's situation at Borussia Dortmund.
Barca have joined long-term suitors Real Madrid in their interest in the Norway international.
Esport 3 says Haaland can leave for a set price of €75m at the end of this season - an agreement which was struck between BVB and agent Mino Raiola when the striker joined from RB Salzburg last January.
Along with the €75m, the buying club would also have to cough up for Raiola's commission.
BVB paid €20m for Haaland, though that fee almost doubled due to fees paid to Raiola and the player's father, Alfe-Inge Haaland.
