Despite dominating in almost every statistical category, Leeds were held to a 1-1 draw by Brentford on a night that saw both goalkeepers gift goals to their opposition.
Also fresh in the memory was their defeat at Brentford, in their third last match of last season, which derailed that campaign’s promotion push.
Nevertheless, Brentford could barely get out of their own half as Leeds dominated the opening stages, with David Raya making saves to keep out Jack Harrison’s drive and a Luke Ayling header.
But Brentford began to make inroads onto the Leeds half, first when Christian Norgaard fired narrowly wide from 18 yards out.
Moments later the hosts were handed the lead after Casilla slipped and let Cooper’s backpass roll under his foot, allowing Benrahma to tap home at the far post.
It was an awful error from the former Real Madrid keeper, whose place in the side is already under scrutiny following some recent shaky performances.
Raya was back in action to tip Pablo Hernandez’s fierce volley over the crossbar, but he was partly culpable when Cooper equalised for Leeds seven minutes before the interval.
Raya came for, and missed, a corner and as the Bees failed to clear their lines the ball dropped to the Whites skipper who leathered it into the back of the net.
After the break Raya gathered Helder Costa’s low drive and Patrick Bamford fired over from the edge of the box.
Bielsa threw on January recruit Jean-Kevin Augustin for the final 15 minutes but the closest they came to a winner was a Hernandez effort which was deflected over the crossbar as both sides had to settle for a point apiece.
