Manchester City striker Sergio Aguero could leave the club due to his frosty relationship with manager Pep Guardiola, Marca reports.
His fee is expected to be around the €70 million mark, with Real Madrid monitoring the Argentina international's situation.
The 29-year-old has a €200 million release clause at Camp Nou, but Guardiola believes that a bid of €56m will be enough to convince Barca to sell him to the Premier League leaders.
