Real Madrid president Florentino Perez is desperate not to lose Zinedine Zidane this summer.
Zidane, after spending last term as coach Carlo Ancelotti's No2, is becoming increasingly determined to launch his management career and flirted with a move to Bordeaux before the World Cup.
El Confidencial says Perez doesn't want to lose the Frenchman and is considering offering him the Castilla job.
The Real Madrid Castilla were relegated from the Segunda Division last season under caretaker coach Manolo Diaz.
