Sven Goran-Eriksson's men are enjoying an impressive run of form of late, having picked up wins in four of their last six Championship outings - including a three match unbeaten run at home - whilst their opponents come into the clash on the back of three straight defeats.
The Blades also have the lowest goals for record in the Championship, finding the net just 10 times so far this season. The Foxes look to have found a remedy for their defensive frailties, with two consecutive clean sheets against Preston and Barnsley.
Leicester have no fresh injury problems and should boast a strong starting eleven when the teams kick off at 7:45pm.
Skipper Matt Oakley should be back in contention after recovering from the knee injury that kept him out of the squad for the trip to Barnsley on Saturday.
Meanwhile, impressive Portuguese defender Miguel Vitor - who scored his first goal for the club at Oakwell - missed training on Monday with a bruised knee but is expected to be fit.
Also, Darius Vassell is expected to make his second appearance for City tonight after lasting just over an hour on his City debut at the weekend.
