Sharp has found first-team opportunities limited for the Blades this season, although he did come off the bench – and hit the post – in his boyhood club’s 2-0 defeat at Manchester City on Sunday.
Sharp was linked with a return to Leeds United in the national media this week.
But Blades boss Wilder, speaking at his pre-match press conference ahead of Thursday’s trip to Anfield to face champions-elect Liverpool, insisted any conversation about his future would be a short one.
“There are hundreds of reports linking people everywhere,” Wilder said.
“Billy’s a fantastic player, he doesn’t want to go anywhere and I don’t want him to go anywhere.
“So as far as I’m concerned that’s the end of the conversation with him.”
