Danny Wilson believes the race for promotion to the Championship will go to the wire.
With four points separating first from seventh, League One is arguably going to be the most difficult division to get out of, but Wilson is determined to make sure his team is best equipped to win the race for a return to the second tier.
Speaking ahead of the weekend's clash at Boundary Park, where he expects relegation-threatened Oldham Athletic to provide the Blades with a stern test, the Gaffer commented: "The fact that there have been three leaders of the division in the space of a week suggests things will continue to change at the top.
"Our aim remains to stay in the shake-up and, obviously, we want to keep our heads above our rivals if possible. I think it could all go down to the wire and we have to make sure we are ready to fight all the way to the end.
"On Tuesday only Doncaster won in the top six, this weekend everyone could go and win - that is how things seem to go in this league. It is a funny situation that develops in a football season, when things look to be plain sailing you drop points and all of a sudden you are in the pack again.
"What we can't do is get too deflated about what has happened in the past, because we can't change that.
"Our immediate focus is now, another tough game at Oldham, who will be fighting for their lives and come into the game on the back of an excellent FA Cup run, which ended at Everton in midweek."
