Liverpool youth coach Rodolfo Borrell has criticised the "unacceptable" standard of the club's academy.
Borrell's assessment is that it will take two years before the set-up is close to the right level.
"The reality of what we found here was unacceptable," said Borrell, who joined nearly a year ago having previously worked with Cesc Fabregas and Lionel Messi in Barcelona's youth system.
"The under-18s had no centre forward, no balance, no tactical level, no understanding of the game.
"We are working hard, but you can't change things overnight.
"I think we have made a lot of progress over eight months, but we need to improve a lot more to get more players into the first team.
"I think if we keep working hard maybe in two years somebody can appear in the first team."
Borrell's brief from Liverpool boss Rafael Benitez is to develop more English players.
This week the club signed England youth international Jonjo Shelvey from Charlton, who will go straight into the reserve squad, as they try to seek to redress the balance having previously brought in a number of foreign hopefuls.
"I agree - the best players to defend the Barca shirt are Catalan players, the best players to defend the Liverpool shirt are English players," Borrell told BBC Sport.
