The Hornets ended a four-game winless run last time out and are fifth in the table, 10 points better off than lowly opponents Coventry, who have two wins from their 10 matches.
Ismaila Sarr's stoppage-time strike in Watford's 3-2 win over Stoke City on Wednesday had the feel of a truly massive goal.
Vladimir Ivic's side were heading for a third draw in four matches, the other game in that sequence ending in a 1-0 loss to Barnsley.
However, thanks to Sarr's fourth goal of the campaign - a good finish into the bottom corner - Watford are all of a sudden in a far healthier position in the table.
All going well, Ivic's men could enter the final international break of the year second in the division - a position they will gladly accept come next May.
While Watford were celebrating a late winner in midweek, Coventry were ruing their luck as Lyle Taylor scored a 97th-minute penalty to earn Nottingham Forest a 2-1 win.
That crushing loss came on the back of a 3-2 win against league leaders Reading - the Sky Blues' only victory in eight outings.
Mark Robins described the loss as a "big lesson" for his side before switching focus to this trip to Vicarage Road, where Watford have won four and drawn one of their five matches.
Indeed, they have picked up more points at home (13) than any other side in this season's Championship.
That is also the same tally they had from their first five home games in their last Championship campaign in 2014-15, in which they were promoted.
Coventry have lost three consecutive away league games, meanwhile, which is their longest such run since December 2018, when they lost four in a row.
No wonder Robins has labelled this a "huge test" for his side, then, in what will be the first league encounter between the sides since a couple of goalless draws in 2011-12.
Watford Championship form: WWDDLW
Coventry City Championship form: LDLLWL
Without Pedro's four league goals this season, the Hornets would be six points worse off - only Brentford's Ivan Toney (8) has earned his side more points with his goals this term.
Matt Godden, who has four goals and two assists in 10 Championship starts this season, will once again lead the line for the visitors.
Watford possible starting lineup:
Foster; Cathcart, Kabasele, Wilmot; Femenia, Hughes, Capoue, Cleverley, Sema; Gray, Sarr
Coventry City possible starting lineup:
Marosi; Rose, McFadzean, Ostigard; McCallum, Sheaf, Hamer, Giles; Allen, O'Hare; Godden
We say: Watford 2-0 Coventry City
These sides experienced contrasting emotions in midweek, with Watford earning a late victory against Stoke and Coventry losing to a last-gasp Forest penalty.
City have collected one point from a possible 15 on their travels this term, while Watford have 12 home points from 15, so we are backing a routine victory for the Hornets.
