Real Madrid captain Sergio Ramos would see himself replace by a Spanish defender.
Ramos insists he has no immediate plans for retirement, but does have a preference on who should succeed him.
"Once I stop, there are definitely players who want to take over," he told TUDN.
"There is always the opportunity to buy new players in the market - and also foreigners.
"However, I would say that I think Real Madrid should keep their Spanish base. We must not lose our identity."
