Shackleton has stepped into Leeds starting line-up in the absence of Adam Forshaw in recent weeks and the youngster has been highly impressive.
Shackleton’s showings have earned him plenty of praise, with the 20-year-old proving he already has the ability to make an impact on Leeds’ first-team.
And Bielsa admits that he has been very impressed by the progress that the Leeds youngster has made.
“Shackleton can consider himself as one of the 11 starters,” Bielsa said.
“The 11 starting positions, one player can build it. I can build it if I can put one player or another player and they make the team work in similar ways.
“The good thing about Shackleton is, when he plays, the team works, even if I play another team. This is very good for one player of 20 and it’s difficult to achieve this.
“There are a lot of young players with skills to play in the Championship. Maybe they have played matches, maybe they play well, but being part of the 15/16 who can start is a new level and Shack is there.”
Forshaw is set to return to fitness for Leeds this weekend, so it will be interesting to see whether Shackleton still keeps his place.
Bielsa is a big fan of Forshaw, who started this season in fine form, before injury struck.
Leeds take on Charlton Athletic tomorrow, as they look to extend their lead at the top of the Championship table.
Bielsa’s side have started the season in excellent form, although they head into the game at the Valley having won just once in their last four outings across all competitions.
