Watford, who beat Norwich City 2-1 at home last Tuesday could give debuts to striker Les Ferdinand and Midfielder Carl Fletcher.
Ferdinand who is a much traveled striker has been persuaded to come out of retirement to play for the Hornets after playing out his days at Reading last season. During his long and established career can name Newcastle, Queens Park Rangers and England as his former clubs.
Fletcher has joined on loan from West Ham United and is likely to make his debut. However they could be without Daruis Henderson and Gavin Mahon. Striker Henderson is currently out with a thigh injury whilst Mahon continues with his knee problem.
One notable squad member of the Watford line-up is former Blades Winger Paul Devlin, Birmingham born Devlin joined the Blades from the Blues during the 1997/98 season before re-joining them in February 2002. During his Bramall Lane stay he played 139 (+ 26 as sub) and scored 29 goals.
Possible Hornets Line-Up: Ben Foster, Jordon Stewart, Malky Mackay, James Chambers, Clarke Carlisle, Matthew Spring, Anthony McNamee, Paul Devlin, Blizzard, Ashley Young, Marlon King.
Neil Warnock welcomes back striker Danny Webber, the former Watford and Manchester United man has been out since the Preston victory three weeks ago with a calf strain. This proved to be an unfortunate injury as Steve Kabba has hit top form and looks impossible to drop.
However the United boss could be tempted to field new loan signing Vincent de Paul Pericard, the Cameroon born striker joined the Blades last Wednesday on a three month loan deal which could see him move permanent from Portsmouth.
Webber, who played in three different spells at the Vic (two on loan) signed from Manchester United in March 2002 for a month, two months in June 2002 until he fully signed in August 2003 before the Blades signed him in June 2005.
Through his stay at Watford Webber managed to make 67 (+ 13 as sub) appearances whilst scoring 21 goals.
Possible Blades-LIne-Up: Paddy Kenny, Leigh Bromby, Craig Short, Chris Morgan, David Unsworth, Paul Ifill, Alan Quinn, Phil Jagielka, Nick Montgomery, Neil Shipperley, Steven Kabba.
