Sheffield United boss Chris Wilder was delighted with his side's 1-0 victory over Peterborough which secured them a fourth straight league win.
Striker Matt Done struck the game's only goal in the 13th minute as the Blades climbed into the top six.
Wilder said: "I thought it was a steady performance against real difficult opposition.
"They have hurt teams in this division in the past and it was a difficult shape to play against.
"We got off to a great start and got our noses in front. I thought for the first 25 minutes we were really good, without putting the game to bed.
"Their goalkeeper made two or three outstanding saves in that period. They got a foot-hold in the game, but they didn't really create much in the six-yard box."
Wilder's side were on top in the early stages with Billy Sharp putting an effort off-target, Daniel Lafferty seeing his drive deflected wide and Done forcing Peterborough goalkeeper Luke McGee into a superb reflex save.
Blades goalkeeper Simon Moore produced a fine save down to his right to keep out Paul Taylor's shot on the turn.
Substitute Stefan Scougall went close in the second half when his 20-yard effort was palmed wide by McGee and Moore pulled off a great save to keep out Gwion Edwards' close-range shot.
"Simon Moore made a fantastic save to keep it at 1-0 and possibly we should have taken the game away from the them with a couple of chances we had at the end," Wilder added.
"I thought there were some very good performances. My only criticism was that we didn't take it from one to two and two to three.
"It was a great result and very satisfying against a dangerous team."
Peterborough manager Grant McCann felt his side were always chasing the game after a slow start.
He said: "I thought we started the game really poorly and if you don't start the game well against good teams, you get punished.
"I didn't think we were ruthless enough again. Too many of our shots were powder puff, from long distance with no real power.
"It is frustrating because we are dominating the ball and you can see we are moving the ball really well. We are creating chances, but we shoot from 30 to 40 yards when it could be another pass or a cross.
"Sheffield United sat a little bit deep in the second half, but we didn't do enough to win the game. It's disappointing, but we move on.
"We played well without scoring. The Gwion Edwards chance and the Paul Taylor one in the first half, when we could have just taken a touch and finished it. Chances like that you need to take at this level.
"It's the early part of the season and we know we're not far off where we want to be."
