In terms of Premier League form, both these sides have been poor of late – just seven points taken from the last six games for Manchester Unitedand only two from the same period for Watford.
United boss Ole Gunnar Solskjaer will be pleased to have a few more faces available after missing midweek, when his team could only draw at Club Brugge.
Watford know they can move out of the bottom three if they take any kind of positive result from Old Trafford, though a win would be most welcome after several relegation rivals lost on Saturday.
