Ollie Watkins didn't look to make any excuses after his missed penalty and held himself responsible for thinking about scoring before he took it.
The Brentford forward, who was having objects thrown at him by Leeds fans as he ran up to take the kick, skied his effort over the bar in the closing stages of the first half. A successful spot kick would have put the Bees 2-0 up after Neal Maupay's opener.
It looked as if it would have cost them the win when Dan Bentley's error allowed Ezgjan Alioski to head home but Yoann Barbet's free kick and Ryan Woods' superb strike sealed a 3-1 win.
He told Sky Sports: “It didn't put me off I saw a few things thrown at me but you blank it out. I was thinking about scoring before I hit it.
“I wanted to go high but I put it over the bar. It happens and I'm glad we moved on and go three points.”
He added: “Going into half-time at 2-0 would have made us relaxed. We've done well to turn it around and I'm buzzing for the lads.”
Watkins usually turns away from the keeper before taking it but, in this instant, was facing Andy Lonergan.
