The Blades boss has named an unchanged line-up for his first three games in charge of his boyhood club, but faces Southend tomorrow still looking for his first victory.
But, speaking after Saturday's 1-1 draw at home to Rochdale, Wilder said: "There are no issues. We've been committed throughout and it's a real positive to not pick up any injuries over three competitive games.
"So we have a full group for the game on Tuesday night. We look strong at the end of games; on Saturday we tried to force the issue in the last 15 minutes, after playing 120 minutes in the EFL Cup on Tuesday night against Crewe.
"We've started on the front foot in all three of our games so far and although no team in football will ever have things entirely their own way, we'll be looking for that to continue."
Harry Chapman, the 18-year-old winger who joined on loan from Middlesbrough on the eve of the Rochdale clash, could be in line for his first start after coming on as a substitute against Keith Hill's men.
