Nigel Clough was understandably delighted with the Blades crucial victory over Shrewsbury Town at Bramall Lane on Saturday.
Early goals from Scottish duo Ryan Flynn and Stefan Scougall, with his first in United colours, paved the way for much needed three points.
The Gaffer, who was relieved to see his players get quickly out of the starting blocks, remarked:
"It was a big win for us, an important one too. It wasn't sparking or spectacular at all, but it was a very professional display and that is immensely pleasing.
"We emphasised the importance of a quick start having gone to extra time on Tuesday because we didn't know how long we would last as the game progressed, thankfully we remained professional having gone two goals in front.
"We got the goals early on and looked after our lead which we haven't done previously.
"In the second-half we visibly had a few running on empty and that was to be expected, but we were determined to make Shrewsbury work very hard for a opening and in the end they couldn't break us down."
Clough opted to leave both Chris Porter and Billy Paynter on the bench against the Shrews, with Jose Baxter leading the line and the manager explained his thinking, adding:
"Our selection was focused around how we want to play, Jose (Baxter) is probably the best we have at holding the ball up and bringing other players into the game.
"In Stefan Scougall and Conor Coady we have the legs in midfield and Ryan Flynn and Jamie Murphy prove a constant threat down the flanks.
"Brentford will be a different challenge on Wednesday night and we might need to freshen things up, but we'll see how the lads are after a couple of days rest."
