David Weir pulled no punches in his assessment of the Blades Capital One Cup exit at the hands of Burton Albion at Bramall Lane on Tuesday night.
Speaking immediately after witnessing Chris Hussey's match winning double for the Brewers, Weir remarked: "It is bitterly disappointing to lose the game, especially conceding so late on, which gave us no chance to mount a second recovery.
"The game highlighted a few negatives, so now we must work out and analyse what we can do better to prevent a repeat in the future.
"I thought we played well enough in parts of the game, but obviously in the end I am not happy that we didn't do enough to win the tie and progress to the next round."
Weir pinpointed the 2-1 reversal on some basic errors, but was quick to acknowledge the support the players received from the terraces.
He added: "We want to pass and move, but we need to be win matches, we must strike a balance between those two factors, but in this instance we didn't do the basics well enough.
"The fans have been fantastic, they understand what we are trying to do and they have supported us fantastically well in both home games to date, by remaining patient throughout.
"Ultimately though, as things progress we will be judged on results, so we have to learn lessons from this defeat."
