Watford and Sheffield United played out a 0-0 draw at Vicarage Road on Saturday to leave Quique Sanchez Flores' side at the bottom of the table, still searching for their first Premier League win of the season.
The result extended the Blades' unbeaten run on the road to four games since their return to the top flight -- with three draws and a win -- as jeers rang around the ground from the home fans at the final whistle.
Andre Gray had the best opportunity to put Watford ahead in the ninth minute when Roberto Pereyra set him up for a tap-in but the English striker blazed over from inside the six-yard box from an offside position.
Despite being the home side, Watford were set up to defend deep and it was the visitors who dominated possession and had two shots on target in the first half.
The first few minutes of the second half brought a flurry of chances, with goalkeeper Dean Henderson saving a one-on-one opportunity from Watford's Danny Welbeck before Callum Robinson's half volley at the other end was hit straight at Ben Foster.
Watford's Gerard Deulofeu was introduced in the second half and United manager Chris Wilder brought on striker Billy Sharp in search of a goal but neither side were able to find a breakthrough even after five minutes stoppage time.
