According to RAC1, Barcelona owe Sergio Busquets €20m in deferred salary from back when the captain agreed to delay his wages to help the club with their financial problems.
Busquets's contract at Barca expires in 2023, and there is no plan to offer him an extension, at least for the time being. In this case, the Catalans would have to pay the €20m before the end of the new season.
There have been rumours that Barca might offer another pay cut to the captains, but there have been no concrete talks with Sergio yet.
Busquets remains a key player at Barca despite his age. In the 2021/22 season, the 33-year-old recorded three goals in 50 games for Barca.
