Enda Stevens believes the Blades need to 'manage' games better, particularly away from home.
Speaking after Saturday's reversal at Derby County, the Republic of Ireland international admitted a below par second-half showing proved costly at Pride Park.
He commented: "It was disappointing, we got off to the worst start possible, conceding in the first minute.
"But for the remainder of the first-half we really got hold of the game and put Derby under some serious pressure.
"We deservedly got ourselves back on terms, but we didn't repeat the first-half showing in the second period, we struggled to get back up to the tempo and that was frustrating."
Stevens added: "It was one of those games, we need to manage situations better, you can't keep such an high intensity going for 90 minutes, so we perhaps needed to keep hold of the ball better and frustrate them.
"Unfortunately we got caught, conceded a poor goal and there was no way back.
"We don't want to have those slow starts that we had at the beginning of the season, we've set our own standards and we must build on what has a really good start."
