Nigel Adkins felt on another day the Blades could have easily won Saturday's clash with Swindon Town at Bramall Lane.
Billy Sharp got his seventh goal in as many Sky Bet League One appearances from the penalty spot to give United an early advantage, but in the end the Blades were forced to settle for a share of the spoils after Brandon Ormonde-Ottewill's late leveller for the visitors.
Reflecting on the stalemate against the Robins, Adkins remarked: "We got off to a very good start, Paul Coutts did excellently to win the penalty and Billy (Sharp) dispatched it emphatically, but he could have scored again moments later from Martyn Woolford's free-kick.
"We are fully aware of how Swindon play, they are very adventurous in possession and move the ball quickly, so we had to keep our shape and remain focused.
"But at the same time we endeavoured to keep two strikers up field because if we caught them in possession it was important we had the bodies forward to capitalise and we had chances in the second-half to get what I believe would have been a game clinching second goal.
"We knew we were getting pegged back towards the end of the first-half so we matched them up with a diamond in midfield after the break with Coutts at the tip and it worked well without us scoring again."
The Gaffer added: "We were resolute and Luke Williams, Swindon's manager complimented us on that after the game, they got in behind once and unfortunately for us scored the equaliser.
"Chris (Basham) picked up a knock and has a couple of niggles, whilst Dean (Hammond) had been booked harshly and was at risk of being shown a second yellow card at the time so we brought him off too.
"The substitution I will reflect on is bring Couttsy off, when it turned out that we needed fresh legs in attack, but at the time it felt like the right decision to make.
"We needed energy in midfield, Ryan Flynn gave us that whilst Jose (Baxter) and Louis (Reed) are players who have deserved an opportunity and give us the ability to use the ball better.
"But it is just a shame a couple of things went against us and we drew a game that looked like we were going to win."
