The Spaniard is currently in charge of Real Madrid Castilla, and few people know the club better than him. However, the Los Blancos hierarchy believe that the time is not ripe for him to take charge right now, given that the club is going through turbulent times and Raul lacks managerial experience at the highest level of the game.Understandably, Mauricio Pochettino is the preferred candidate.
