Chris Wilder hailed Tuesday's success in the face of adversity as one of the best in his time as manager of the Blades.
Speaking after an eighth straight home league victory, despite playing over 55 minutes with ten-men, following the dismissal of Gary Madine, Wilder was clearly delighted and relieved.
He remarked: "In the days of people talking about playing between the lines and fancy, attacking football, for us to produce a defensive performance like that is really heartening.
"There is no wonder boys consistently keep clean sheets. If we were to go down to ten-men, the last team I'd want to be facing is Brentford.
"I'd put them as the best team in the division at moving you around with the ball, they are a really good team so to defend like that, with that attitude and to put our bodies on the line like we did, means the result is right up there for me.
"We showed desire to keep the ball out of our net, to keep our shape and most importantly to get a result for the football club.
"It looked like a penalty from my angle, I wasn't surprised it was given but this was always going to be a very tough game.
"Brentford have recovered well under Thomas (Frank) have a difficult start and they are a talented group, so the task was made doubly difficult when Gary (Madine) was sent off."
Wilder added: "I didn't need to see the tackle again, if the Rotherham skipper gets sent off for his tackle on Saturday, then Gaz's challenge is a red card too.
"He's devastated in there, he's disappointed in himself and I thought he was outstanding in the first half hour, he linked play and we were enjoying plenty of the ball.
"We tried to clog up the midfield but the kept coming and coming and I thought it was a matter of time. We knew we'd got to change it and we did. We brought Billy on up front and it helped us get up the pitch.
"We had an out, we were better at the start of the second-half, we had chances and we always felt we could get a second goal, we weren't bothered where it came from because we really had to dig in and we were backed by excellent support."
