The Red Devils can leapfrog Tottenham and former manager Jose Mourinho if they take the points, which would leave them three points off fourth.
Watford, meanwhile, know that even a point is enough to move out of the relegation zone on goal difference, while a win takes them 16th.
Form isn’t skewed toward one particular team; United have won just once in the last four in league play and Watford haven’t won any – both teams have just two league wins in 2020 so far.
