Barcelona defender Gerard Pique has paid tribute to their La Masia youth system.
Pique says Barca's success is due to the work being done at junior level.
"We have had the luck of having everyone coming through the youth ranks," Pique said.
"Barca has always found it difficult to compete with Madrid. In the last few years just how much have Madrid spent?
"At Barca we have had so many players that have risen through the youth teams and have been free.
"If that had not happened then we would not have been in a position to compete for trophies. On an economic level we cannot compete with Madrid."
