Chris Wilder rates West Bromwich Albion as one of the strongest teams in the Championship and will be delighted if his Blades remain above the Baggies on Saturday evening.
Ahead of the televised encounter at the Hawthorns, United sit second in the table, one point above fourth placed Albion.
Previewing the game, the United chief comments: "The big tests keep rolling on. Villa was one, one that we ultimately didn't come through but a lot of good things happened that day, then there was Middlesbrough and how we would cope in the last eight minutes, then there was Reading when we changed the side, I reckon people will have been looking at that and wondering if we had enough but the Reading game was one of a few outstanding performances of the season.
"Hopefully we will produce another outstanding performance against West Brom. Right the way through the last 13 games the tests will come thick and fast, we've got to enjoy and embrace it."
Wilder adds: "I understand the quality of the West Brom team. Darren Moore came in at the back end of last season in the Premier League and if they had a few more games he would have possibly kept them up.
"West Brom, for me, out of the ones that got relegated, are the best equipped for going back up, in terms of experience on the coaching staff, quality of the players and the quality they have brought in. We are delighted to be above them at the moment and will be even more so if we are after the game on Saturday night."
