Chris Wilder insists the Blades could face one of their toughest assignments of the season when Millwall arrive at Bramall Lane on Saturday.
Speaking ahead of the clash with the Lions, the Blades boss remarked: "The picture at the top of the division changed again in midweek, we'd like it to change again obviously, but we've got to take care of Millwall.
"I've got an awful lot of admiration for what Neil (Harris) and his team have done down there in London.
"They came up with us and had a fantastic season last year. It's been a stop start campaign for them this time around though, they've lost a couple of players and a few injuries have affected them badly too."
Wilder added: "They always give it everything and they always leave everything out there, I understand that and my players understand that, we will have to play well to win the game.
"Their players might be a bit edgy given their circumstances and one of their players says ours might be too.
"They've got a goal in them too, especially with a local boy in Lee Gregory coming back to his boyhood club."
