John Fleck says the Blades will have to be at their best to get the better of Rotherham United in Saturday's Yorkshire derby.
Paul Warne's Millers presented the Blades with one of their toughest games of the season at the New York Stadium, a fact that isn't lost on the Scottish midfielder.
He remarked: "They are a dangerous team for us to play against, we were actually quite lucky to get a point there earlier in the season.
"We can only comment on them from what we saw at their place, they probably deserved to win that game in all honesty.
"Looking back now it was probably a good point. They will come, work hard and they've got a decent squad of players."
Fleck added: "We know it will be tough, they are fighting at the bottom, we're fighting at the top, it should be another entertaining game.
"They've got some good players, the likes Smith and Vaulks and Taylor out wide, it'll be another battle, but one we're confident of coming out on top."
