United haven’t tasted defeat in league competition since losing at Millwall back in August, and sit just three points off the automatic promotion places after Saturday’s 2-1 victory over MK Dons at Bramall Lane.
And Wilder, who admitted that losing Matt Done with a facial injury was a “big blow” before the game, said: “We had to change our shape four or five times during the game, but we said before the game we needed a win.
“We got a result at Bradford which we were semi-happy about, but we need to win home games, especially against competitors.
“Regardless of their league position, MK Dons are a competitor.
“They have Championship players. I know there has been a change of manager, but they have been playing this system for five years, and had success.
“We have been at it for three months.
“We have come a long way in a short space of time, but there’s still more to come from us.”
Wilder, who is expected to be in attendance when United’s youngsters kick-off their FA Youth Cup campaign against Crewe Alexandra tonight at Bramall Lane (7pm), added: “MK made us work.
“They’re in a false position in the league; we knew that with the players they have got on the pitch.
“They keep possession, but I have to say I don’t think they created many clear-cut chances.
“Their shape is dangerous to play against, and it was a dangerous game. It was a tough game. Even though we are at the back end of October, it was a big result for us to beat them.”
Stefan Scougall, recalled to United’s starting line-up in place of the absent Done, made the most of his opporunity; first, netting United’s opener before setting up Billy Sharp for the winner.
But when asked if the young Scot had repaid Wilder’s faith, the Blades boss insisted: “He doesn’t have to repay me anything.
“He’s an employee of the club and a good player.
“He’s working extremely hard for the team and when he gets the ball he’s positive.”
The Hualing (South) Stand will be open for tonight’s Youth Cup fixture, with Blades season-ticket holders entitled to free admission. Adult tickets are £3, and concessions £1.
Saturday’s U18 derby against Sheffield Wednesday, at Shirecliffe, will now kick off at 11.30am.
