Spain youth coach Luis Milla feels youngsters face an uphill struggle at Real Madrid.
Real boss Jose Mourinho's regard for the Castilla has come under scrutiny this season.
"From the outside, all you can see is the gap between the youth and first-team players. Making the jump to the first team is very difficult," Milla said during the Second Conference in Support of Aid for Chad.
"There's a certain level, and the coach, who never tires of saying so, has a clear policy of not betting on the youth players."
