Real Madrid are willing to sanction a number of departures in the January transfer window, claims Mundo Deportivo.
Asensio and Carvajal could start negotiating pre-contract agreements with other clubs in January as their contracts expire next summer.
Madrid are hoping to at least get something from their sales rather than see these players leave for free.
They have reportedly tabled a contract offer to Asensio, but there is yet to be any progress on that.
Los Blancos are unlikely to be able to sell Eden Hazard in January, with the Belgian ruling out a winter move.
