Sheffield United consolidated their place at the top of Sky Bet League One with a 4-1 win at Southend.
Ethan Ebanks-Landell headed the Blades into an early lead after just two minutes but Simon Cox levelled for the Shrimpers, who were on the back of a 10-match unbeaten run, in the 19th minute with his fourth goal in as many games.
Defender Jack O'Connell put United back in front four minutes before the break when he converted a free-kick from Mark Duffy and Caolan Lavery slotted in a third before Kieron Freeman wrapped things up.
Substitute Jermaine McGlashan netted a late second for the Shrimpers with two minutes left.
"This was by far the toughest of the wins and it's a big result for us," said Wilder.
"I know how difficult it is to win at Southend because I don't think I've ever got a result here personally.
"Our performance in the second half took it to a different level and we've shown a lot of good attributes.
"We got pegged back by their equaliser when we should have been 2-0 up after five minutes but then we really took the game away from them
"They are a dangerous side and they battered us at our place so this is a good result but we won't be getting carried away about it."
