'You don't always get what you deserve', was Chris Wilder's assessment after Friday's cruel home reversal against Bristol City.
Leon Clarke netted his 14th of the season to cancel out Jamie Paterson's opener, only for Aden Flint to win it for the Robins at the death.
But Wilder, who saw John Fleck dismissed for a challenge on Korey Smith just after the hour, was in bullish mood despite the defeat.
He remarked: "I believe we did more than enough to win the game. The reaction of the players epitomised what this club is about, from the manager, to the staff, to what those players gave out there.
"Bristol City are in great nick, they comfortable turned Middlesbrough over last week and that was a deserved victory against a side that thought they'd win the league.
"They've got several good players and are flying, but I thought some big, big decisions went against us.
"The big lad who came on at half-time was committing fouls for 20 minutes before getting a yellow card and at the death there is a clear high boot on Jack O'Connell as he heads clear in the build-up to Flint's goal and he isn't stooping at all."
The Blades boss added: "Their goalkeeper has made some unbelievable saves, we've hit to woodwork several times and although I hate losing, I loved the way my team played.
"There have been a few questions asked and rightly so, have teams worked us out and has the bubble burst?
"People will be thinking we've had an excellent start and that's us done, but those players responded to any negativity from anyone who wants to throw it at us in great fashion and unfortunate you don't always get what you deserve."
