Nigel Clough says the Blades are looking forward to testing themselves against the frontrunners in League One over the next three matches, starting with second-placed Brentford on Tuesday night.
Looking ahead, the United manager remarked: "The next three matches are going to be interesting, after those we will have played the current top four at home in succession and it will be good to be able to gauge our progress.
"Wolves showed why they are top of the league when they came here and Brentford are hot on their heels, we then follow that up with Leyton Orient and Rotherham, it is a big spell for us and a good test.
"We are confident as we always are going into games at Bramall Lane and hopefully we can get a decent points return because we certainly don't want to be entering the semi-final on the back of a run of defeats, we still have plenty to play for."
Prior to welcoming Mark Warburton's Bees, Clough played down the Blades hopes of reaching the end of season play-offs.
The Gaffer concluded: "We are seven points behind Peterborough with just eight games left, so we need to win three more than them and that is unlikely in a short space of time, but we will keep plugging away.
"I am just delighted that given where we were a few months ago, that our season is still very much alive at the beginning of April."
