Nigel Clough was understandably bitterly disappointed following Saturday's unfortunate 2-1 reversal at Notts County.
Conor Coady gave the Blades an early lead at Meadow Lane, but goals from Enoch Showunmi and Mark Fotheringham ensured the points didn't come back up the M1, much to Clough's annoyance:
"I don't feel the final scoreline was a fair one, but we didn't make the most of the chances we created.
"We played well in parts and matched Notts County when the game was a battle, they have scored from two crosses but rarely troubled us otherwise.
"Nothing really pleases me, given the defeat, but like a lot of other teams, including Aston Villa, we haven't given much away defensively, so we are frustrated to leave with nothing."
The Blades boss felt key decision went against United, adding: "On the day we didn't get the run of the ball and even more so we didn't get a lot of decisions in our favour.
"Tony (McMahon) has a shot in the first-half, we saw it from where we were on the touchline, it is blatant handball and penalty.
"That was just one puzzling decision though. Our supporters who follow us away from home will be wondering why these decisions, like the penalty at Walsall, are going against us."
Clough concluded by saying his team should have built on Coady's early opener, remarking: "It was a brilliant goal we scored inside two minutes, but we should have doubled that advantage in the first ten minutes. We needed to take charge of the game whilst they were rocking but we didn't manage to do so.
"When you are on top it is crucial you take control of the game."
