SHEFFIELD United boss Nigel Adkins is preparing his players for a "tough" test against Millwall at Bramall Lane on Saturday.
The Blades climbed up to fifth place in the Sky Bet League One table after an impressive 3-0 win over Fleetwood last weekend and have lost just one of their last eight games.
United were the pre-season title favourites and Adkins, who gained promotion from League One with Scunthorpe and Southampton, has set them back on course after a difficult spell in September that saw them fail to win in four games.
Millwall are unbeaten in three games and have lost only two of their last 10, but travel to Sheffield with a number of injury worries.
Midfielders Jimmy Abdou and Ed Upson are already out, and Shaun Williams could also miss the game after he had to be substituted when he suffered back spasms in the 1-1 draw at Blackpool.
However, Adkins revealed he has done his homework on the Lions.
He told the Sheffield Telegraph: "Millwall, we've watched them on the videos, and it looks like being a really tough game. So far, they've kept two really solid banks of four, they don't give many opportunities away and they are very good on set-plays defensively.
"We're scoring goals, which is important, but we need to be really on it every weekend. We need the fans to be supportive of us because, it appears, these could be difficult opponents to break down."
