Bielsa, who is held in great regard by the likes of the younger generation of coaches such as Pep Guardiola and Mauricio Pochettino, said he was satisfied without being over the moon at how his team played.
"The opponents dominated at the beginning of the game and at the end of the game, but between these two moments, without being excellent, we did an interesting performance," said Bielsa.
"It is not convenient to make comparisons with other teams at this moment in the season.
"It was hard for us to find a solution to the project of play from Sheffield United," added the 63-year-old former Argentina and Chile national coach.
Bielsa, though, will be worried by another influential defender, club captain Liam Cooper limping off injured in the first-half, joining Luke Ayling on the treatment table.
Leeds turned on the pressure in the second-half, Polish international Mateusz Klich forcing Henderson into a smart save as the hour mark approached.
Bailey Peacock-Farrell came to the visitors' rescue soon afterwards the Northern Irish international goalkeeper saving with his feet from David McGoldrick.
The previously impeccable Henderson gifted Leeds a goal with eight minutes remaining. Desperately trying to save a poor back pass by John Egan from going for a corner, he passed it straight to Clarke.
The 18-year-old forward kept his head and laid it across the area to Hernandez who made no mistake.
