The Whites had the initial breakthrough with the goal from striker Patrick Bamford.
And the visitors were reduced to 10 men, inside the first fifteen minutes, after Cedrick Kipre was shown a red card.
However, Paul Cook’s men were able to subdue the Whites, as Gavin Massey scored a brace in the 2-1 comeback win.
Following the defeat, the Argentine manager expressed his disappointment over the result. (h/t Leeds United site)
“It is not a game that you can analyse, because you have games like this that you have to win.
“The result tells a lot about me and condemns seriously my work.
“You have no explanation that could justify a loss like this, it was a game we had to win and it was a game that we could win and we didn’t win it.
However, Bielsa promised his side would bounce back in the upcoming games.
“I am very sad, but I am full of motivation and I’m ready to work again immediately in these games.”
The Whites’ promotion race looks an unpredictable one now, after being handed a loss in the crucial stage of the league.
Furthermore, the defeat allowed the Promotion rivals Sheffield United to leapfrog Leeds to second in the Championship table.
