Real Madrid are reportedly keen to tie Dani Carvajal and Marcelo down to new contracts.
At present, right-back Carvajal's deal at the Bernabeu is not due to expire until the summer of 2019, but Los Blancos are prepared to extend that by a further 12 months, according to AS.
As for Marcelo, the report adds that Madrid hope the Brazilian left-back will accept new terms that run until 2021.
The defensive duo made a combined total of 95 appearances in all competitions last season.
