Real Madrid coach Zinedine Zidane feels they can promote from within to replace Isco.
The Spain international is being encouraged to leave Real Madrid this summer after falling off the first team map this season.
At 29, Isco is prepared to depart and has instructed his agent to sound out interested clubs, reports AS.
And rather than buy a replacement, both Zidane and his coaching staff believe they can promote from within to fill the void.
Sergio Arribas, 19, has been identified as the Castilla prospect good enough to step in for Isco for next season.
