18:59 - Hi everyone I am Danial Kennedy and welcome to VAVEL's coverage of Derby - Manchester United
Sir Alex Ferguson’s side dominated at Pride Park seven years ago in what was the fifth round, with goals from Nani, Darron Gibson, Cristiano Ronaldo and Danny Welbeck cancelling out Miles Addison’s effort and giving them the comfortable 4-1 victory.
The six times that two sides have met in the history of the illustrious competition, Derby have lost every time - their most recent meeting back in 2009.
Nonetheless, Clement does have head-to-head concerns and he will be wary of Friday’s opponents if their recent record with the Red Devils in the FA Cup is anything to go by.
There are no fresh injury concerns for Clement, with Max Lowe, Craig Forsyth and Will Hughes all long-term absentees while new signing Marcus Olsson will be available.
Experienced midfielders Michael Carrick and Bastian Schweinsteiger could make their returns from injury and suspension respectively. However Ashley Young, Marcos Rojo and Phil Jones are all out.
The Italian’s absence will open another possible opportunity for youngster Guillermo Varela in the first team though, while Cameron Borthwick-Jackson is in contention for a place at left-back.
Regarding team news, United’s long injury list continues to grow as, last weekend, full-back Matteo Darmian limped off in the defeat to Southampton with what proved to be a broken rib and a punctured lung - ruling him out of this fixture.
However, van Gaal's job was thrown into turmoil once again at the weekend with a late goal from new signing Charlie Austin giving Southampton a narrow 1-0 victory which brought with it a barrage of boos at Old Trafford. Consequently, van Gaal will be hoping to get back on track on Friday night.
They have not suffered defeat since that day at the Britannia Stadium though, their five games unbeaten topped off by the 1-0 victory over bitter rivals Liverpool.
Van Gaal has been under real pressure for a number of weeks after a terrible run going into the Christmas period, with the 2-0 defeat to Stoke City seeing people call for his sacking.
For the visitors, on the other hand, it has been another week to forget for them and manager Louis van Gaal as the Dutchman’s job hangs by a thread once again.
They fared better in the cup when they bypassed Hartlepool United in third round. They found themselves behind through a Jake Gray goal, but strikes from Jacob Butterfield and Darren Bent gave them passage with a narrow 2-1 win.
The fashion that they have been losing in will also be a concern for manager Paul Clement - the team shipping seven goals in the last two matches, with 3-0 and 4-1 defeats to Birmingham City and Burnley respectively.
However, they have only managed two points in their five matches since, which has seen them drop right down into fifth - seven points adrift of current leaders Hull City.
Derby have endured a fall from grace lately. At the beginning of the season, and midway through it, they looked a certain bet to be promoted back into the top flight of English football for the first time since the 2007-08 campaign, with their 2-0 victory over Fulham on Boxing Day sending them top of the table.
Hello and welcome to VAVEL's live coverage of tonight's FA Cup fourth round tie between Manchester United and Derby County. The match will take place at the iPro Stadium, with kick-off scheduled for 7:55PM.
