The Spanish top-flight chief says the Blaugrana will need to "to restructure their debt" in order to keep hold of the six-time Ballon d'Or winner
La Liga president Javier Tebas has warned that Lionel Messi can only be registered for the 2021-22 season if Barcelona reduce their wage bill.
Messi's future remains the subject of much debate as he approaches the end of his current contract with the Blaugrana.
The Catalan giants announced debts in excess of €1 billion (£858m/$1.2bn) in January amid the loss of matchday revenues due to the coronavirus pandemic, and Tebas says they will need to cut salary costs across the squad in order for Messi to be eligible for selection next term.
