Chris Wilder admitted Friday's steel city derby stalemate was a fair result.
Speaking in the aftermath of a fiercely competitive fixture that saw clear goalscoring chances at a premium, the Blades acknowledged his side didn't do enough on the night.
He remarked: "We disappointed not to have won the game. It's a missed opportunity for us and it's happened too many times recently.
"It's the last three or four homes games, it's been a similar story, from box-to-box we've been very good, but that's not enough at this level.
"Give the opposition some credit, they came, sat in and looked to hit us on the break as we expected, they turned up and perhaps a few are thinking they short changed the previous manager."
Wilder added: "My boys turn up every game, it's not an ask, it's a must to run around and compete, but Wednesday came and gave it a right go.
"It was a proper derby, we're just disappointed that we've not picked the right pass or made the right run in the final third to get the first goal, if we get that I believe we win the game.
"In the end though, we're indebted to our goalkeeper for a fantastic save at the death."
