Barcelona fans have jeered Frenkie de Jong at the club's training centre.
Manchester United have been tracking the midfielder for months, with new manager Erik ten Hag making him his priority transfer target, and now Chelsea have joined the race and are hopeful of hijacking a deal.
Barca are keen to cash in on one of their prized assets as they look to raise funds amid a dire financial situation. To complicate matters further, De Jong is owed £17million in deferred wages after taking a wage cut to previously help the club financially.
De Jong is standing firm and wants to stay put, and a section of the club's fans are seemingly taken against this as they heckled the midfielder, demanding: "Lower your salary!"
The Dutchman is due £16.8m in wages for the coming season, and then £21m for the 2023-24 campaign.
