Chris Wilder was understandably deflated following Tuesday's late setback against Stoke City at Bramall Lane.
In a game where the Blades were the dominant force throughout, Leon Clarke's first of the season looked to have secured a win that would have seen the Blades regain top spot, only for Joe Allen to snatch the Potters an undeserved point.
And Wilder was frustrated with that late concession, he remarked: "It's a tough one to take, we dominated that game from start to finish.
"On their goal, that's why Peter Crouch has played for England and in the Premier League, not only is he a good player, he's a bright and intelligent one too.
"He's used his experience to win that free-kick, but we've not lined the wall up very well and that's a disappointing one for us, Crouch took our attentions away from getting the wall right, but that's one a small disappointment for me.
"I'm absolutely delighted with our performance, I thought we were absolutely outstanding. Stoke will be getting back on their bus wondering how the hell they've got a result."
Wilder added: "It feels like a defeat, you usually get what you deserve in football, I talked about that on Saturday when we didn't do enough to win the game and we have to learn from our mistakes.
"But we deserved to win that one, we've limited a team full of internationals who are on big money and have come out of the Premier League and they are jumping for joy at the end which I understand why in the circumstances."
