United concluded pre-season with a victory at Doncaster Rovers on Friday, leaving boss Chris Wilder pleased.
Second half goals from David McGoldrick and Billy Sharp secured the win at the Keepmoat.
Wilder said afterwards: "We experimented with the side a little, changed things around, but there were some plus points. Doncaster provided a good test, they moved the ball around, kept players up the pitch, but we improved in the second half.
"Simon Moore did well, he worked harder than we would have liked and made some excellent saves, which is great for him."
The United chief added: "Pre-season has gone particularly well, we've had good periods and not so good periods in the games we've played. We've got a big week ahead of us with players pushing for places."
United have won four and drawn two of the pre-season tests.
