Coutinho cost Barca a guaranteed £105million in 2018 but with a further £40million possibly due in add-ons over the course of his contract.
As things stand it is thought Liverpool are still due another £50m as part of the Coutinho transfer - money which Barca can ill-afford to part with at the present time.
AS says Barca chiefs have suggested the Brazilian playmaker moves back to Anfield to write off the debt without receiving a fee in return.
Coutinho is still a popular figure inside the Reds' dressing room despite his slightly acrimonious exit, which cast him in a negative light with the club's fans.
Whether he would be willing to take him back is another matter, however.
