Stefan Scougall thought the Blades deserved a share of the spoils against Millwall last Saturday.
The Scottish midfielder scored on his first start of the campaign at The Den and was encouraged with aspects of the performance, but admitted the result was disappointing.
He commented: "We were comfortable and dominant for much of the first-half so to only go in on level terms was a bit of a blow.
"We had worked hard to get back into the game and in my opinion we looked relatively comfortable and all set for a point.
"But at the end of the day, it's all about the result, if we can't get three points, then we need to make sure we get one."
On the game's decisive moment, which saw Jack O'Connell penalised for a handball in the penalty area, resulting in Steve Morison netting the winner from the spot, Scougall admitted it was a tough one to take.
He added: "It's part and parcel of the game, sometimes these decisions go against you and often they prove costly."
