George Baldock praised goalkeeper Dean Henderson, following the midweek stalemate with Birmingham City.
Henderson proved to be a reliable last line of defence for the Blades, in a game that saw Birmingham frustrate the home side, before finishing strongly.
Baldock remarked: "We're slightly disappointed and we've probably got Dean Henderson to thank for the points, he made a couple of great saves, but we have to quickly move on now to Preston.
"The one in the first-half was a fantastic save and the one towards the death was even better, so we're delighted for him, but the focus now is Saturday."
He added: "Birmingham made it difficult for West Brom last Friday and they did the same to us. They came and made it a scrappy game and we weren't at our most fluent.
"The first goal is vital and even more so when teams come and sit behind the ball, if we score early they have to come out of the traps and that leaves space which we can exploit."
