Mousset opened the scoring at Molineux in just the second minute, with his fifth goal of the season – from as many starts – and second in two games.
The Frenchman is expected to lead the line again for the Blades tomorrow night, when they take on Newcastle United at Bramall Lane.
And Wilder, speaking this morning at his pre-match press conference, challenged Mousset to keep his standards up ahead of the Blades’ second game of three in the space of seven days.
“All players want to hit the ground running and Lys has done that,” Wilder said.
“He’s still in the early part of his Sheffield United career and it takes time for everyone to settle in, although some do it quicker than others.
“You hope players you bring in will make a contribution and he’s doing that. So are the likes of Callum Robinson, Oli McBurnie and Luke Freeman.
“Sometimes it’s easy to just look at contributions on the pitch but I look a little bit deeper than that, and those lads are really pushing the first-team boys. It has to be that way.
“But Lys is early in his career here and he has to maintain those standards.
“He’s part of a group but he has got an important part to play, and can be pleased with his start.”
