Chris Wilder praised the character of his players, despite Saturday's loss at Wolves.
Speaking after acknowledging his side were comprehensively beaten at Molineux, Wilder remarked: "It was important for us that we stuck in there, it wasn't been defeatist, it's about being realistic and not getting beaten more heavily because physiologically it could have hurt us.
"We've not won any points, but we played an outstanding team in the division who will be in the top-flight next season without a doubt. Possibly they are one of the best Championship sides I've seen in a long, long time."
The Blades boss remains upbeat though, adding: "We couldn't play round them or through them so we tried to go over the top, but the sending off killed it really.
"Our season starts now, we've got to go and beat our rivals in the coming weeks and win football matches consistently over the next 16 games.
"I can't wait for Leeds, I wish it was tomorrow and we need our supporters more than ever now because the players are a bit down which isn't like them.
"I believe we can successful in the coming weeks and it should make it a grandstand finish. But if people want to write us off that's fine because I know my players and I know they still have plenty of fight in them."
