Leeds United's academy has produced recent England internationals Danny Rose, Lewis Cook and Fabian Delph, among others.
Marcelo Bielsa has vowed to continue Leeds United's long-standing tradition of blooding young talent at first team level.
Not for the first time since taking charge, Bielsa spent the early part of Monday afternoon watching Leeds' Under-23s in action at Thorp Arch.
A number of senior players were involved in the game against Nottingham Forest's second string, which ended 2-0 to the hosts, as well as youngsters Jamie Shackleton, Tom Pearce, Jack Clarke and Ryan Edmondson - each of whom have featured prominently in matchday squads this season.
Others, such as Aapo Halme, Jordan Stevens and Robbie Gotts, caught the eye of some onlookers.
"We could say that we have 18 starters - and usually four are missing because they are suspended (or) injured and you substitute these players missing with young players.
"Shackleton, Pearce and Clarke are youngsters that come from the U23s. Leeds has a tradition of forming players and I like to collaborate with the project of bringing young players to the first team. If you don’t watch the games of the youngsters, you can’t see how good they are."
Academy graduates Bailey Peacock-Farrell and Kalvin Phillips have been ever-presents in Bielsa's Leeds team so far.
