Blades trip goes under the microscope...Sheffield United and Millwall meet in a Sky Bet League One encounter at Bramall Lane this Tuesday night (kick-off 7.45pm).
Following their first defeat in 17 League games at Swindon Town on Saturday, The Lions will be looking to bounce straight back at the first attempt, with a victory seeing them draw level with sixth-placed Southend United.
The top-of-the-table Blades will provide the toughest of tests for The Lions, but Neil Harris' outfit will relish the challenge following numerous victories over big-named teams already this season.
The game will be the 51st between the two, with both sides locked on 21 wins each.
Steve Morison's 89th-minute penalty won the game for Millwall earlier in the current campaign. Shaun Williams gave The Lions the lead after 14 minutes, but Stefan Scougall levelled proceedings seven minutes later.
Morison, however, would have the last laugh, as he converted his spot-kick following Jack O'Connell's handball.
The Lions will go in search of their fourth straight win over The Blades after completing the double in 2015/16.
In March, loanee Chris Taylor's 2nd-minute strike earned Millwall three vital points at The Den, whilst earlier in the season, Aiden O'Brien's double either side of a Jose Baxter equaliser secured victory.
A bad-tempered affair in December 2004 saw Kevin Muscat and Paddy Kenny sent off during the half-time interval, with The Blades winning 2-1, whilst 19th March 2002 will be a date ingrained in the mind of a certain Alan Dunne - the ex-Lion made his debut in a 3-2 defeat at Bramall Lane.
Millwall's two biggest wins against Sheffield United came in a 4-0 win in February 1939, plus a 3-0 victory in March 1986 - a game that saw Paul Hinshelwood, Steve Lowndes and Alan Walker find the net.
