Erling Haaland's representatives have visited Barcelona and Madrid for talks.
Agent Mino Raiola and Alf Inge, the father of Borussia Dortmund striker Haaland, initially landed in Barcelona ahead of a meeting with Joan Laporta, who was elected as Barca president last month.
Raiola and Alf Inge Haaland then flew to Spain's capital for further talks with Real Madrid.
The talks increase speculation over Haaland's future, although it is unclear how Barcelona would finance a deal with the club wrestling with huge debt, caused largely by the coronavirus pandemic.
Haaland, 20, is under contract at Dortmund until 2024 but has a reported €75m (£66m) release clause, which comes into effect in the summer of 2022.
