Faced with a tricky set of February fixtures against Aston Villa, Middlesbrough and West Brom, Wilder and his men swept away all before them with conviction.
A haul of 13 points from a possible 15 and four clean sheets lifted them into the top two.
Wilder said: “It’s been a tough old month, we’ve had some really testing challenges so to come through this month, at the business end of the season, with the points and most importantly performances we are delighted and I accept this award on behalf of the football club, players and staff.
“Defensively we have been solid, apart from obviously the Villa game which was part of the month as well which is quite extraordinary that we have got this award. The biggest moment for me was the reaction to that game, which was a real big test for us from a psychological point of view…how we reacted and the way we have done has been first class.
“We lost some big players during the month and changed the team, the players who have come in have been excellent. They are all in good nick individually and as a team we have been playing well and that obviously gives us the opportunity to win games and pick up awards like this.”
George Burley chairs the Sky Bet Manager of the Month judging panel.
He said: “Eleven goals scored and only three conceded in five demanding matches earned the Blades thirteen points in the month.
“This moved them into an automatic promotion spot and dealt a blow to close rivals WBA and Middlesbrough at a very important time in the season.”
Sky Sports’ EFL pundit Don Goodman said: “It’s going to take an incredible effort from one of the chasing pack to prevent it from being a three-horse race for the two automatic promotion spots in the Championship, and despite a disappointing goalless draw against their local rivals Sheffield Wednesday, Wilder has manoeuvred United into a fantastic place with eleven games remaining.
“During February, his side were tactically brilliant in beating promotion rivals Middlesbrough and West Brom by a single goal, all the while being defensively sound. Four clean sheets in five games highlighted their defensive solidity.”
Sky Bet EFL trader Ivor Davies said: “Chris Wilder’s Sheffield United continued their push for automatic promotion, and currently sit in third place just two points off Yorkshire rivals Leeds and four off high-flying Norwich who head the table. United are 7/2 to win the title and as short as 8/15 to be promoted.”
