Real Madrid boss Jose Mourinho has blamed the club's youth system and Madrid Castilla coach Alberto Toril for not providing a useful reservoir of young talent to the senior side, reports ESPN Soccernet.
The Portuguese tactician has himself been criticised in Spain for blocking a route to the first-team, for promising players who have impressed in the B team. But, in his defence, he said that the differing systems played by the two sides, makes a transition into the seniors much more difficult.
"We play with a different system, they have another model," said Mourinho. "There are Castilla players that play in positions that do not exist in the first team, like Jese (Rodriguez) who plays as a 'nine and a half'.
"Also, our wide players play further forward, and in Castilla they play a 4-4-2. There is limited common ground in terms of the style of play, and the kids are the ones who end up paying the price."
Madrid's second-string were promoted to Spain's Segunda Division last season under Toril, for the first time since 2007, and currently lie 10th in the table with 15 points from their first 11 games.
Whilst there success is encouraging, Mourinho questioned whether the focus at that level should in fact be on winning games, or rather developing players, so they are ready to play at the Santiago Bernabeu.
"Toril knows everything that I have spoken to you about," he explained. "He knows that with me Nacho will never be a centre-back, but he has his independence.
"He decides if it is more important to finish fourth, fifth, sixth, seventh or eighth in the Segunda, or to help a player to develop so he can come through to the first team."
After opting to rest six first-team regulars - Iker Casillas, Sergio Ramos, Pepe, Xabi Alonso, Mesut Ozil and Cristiano Ronaldo - for tonight's Copa del Rey clash against minnows Alcoyano, Mourinho has called up three promising youngsters who he believes still have the potential to break into the Real Madrid set-up.
"If a player of 23 or 24 years has not reached the level to be in Madrid's squad, he will not arrive at 26, 27 or 28. If he is younger, you are expecting that he will develop completely and can reach the team.
"Fabinho (19) is at the point of arriving or not. The same with Jose Rodriguez and Alex. They have potential and the age to end up as first team players."
