Bielsa, who was appointed the Leeds head coach earlier this summer, has been impressed with Tom Pearce, Tyler Roberts, Jamie Shackleton and Conor Shaughnessy.
“[Tom] Pearce is one of the youngsters,” Bielsa told Leeds Live when asked which of the Leeds youngsters he rates the highest.
“Tyler Roberts is a young player too. [Jamie] Shackleton is also a youngster. [Conor] Shaughnessey also belongs to this group.”
Shaughnessy has played only a handful of matches for the Leeds first team so far in his career, but the 22-year-old has already made a good impression.
The versatility of the Republic of Ireland Under-21 international to operate as a central defender or as a central midfielder is also a boon for him.
Jamie Shackleton is a talented midfielder, and Bielsa’s comments suggest that the youngster could get chances from time to time this season.
Tom Pearce did well during the back-end of last season, and the 20-year-old - who can operate as a left-back or as a left wing-back - can only improve under Bielsa this season.
As for Tyler Roberts, the 19-year-old striker - who can also play as a winger - struggled with injuries following his move from West Bromwich Albion in the January transfer window, but the teenager will be a key player for the Whites this season.
