Watford missed the chance to go top of the Championship as they played out a goalless draw against Nottingham Forest at the City Ground.
In a first half of few chances, Forest almost took the lead when Cafu picked out Joe Lolley who saw his shot deflected wide.
Lyle Taylor went close for the hosts after the break when he headed over the bar from close range.
Watford remain in third, having failed to capitalise on leaders Norwich's defeat by Luton Town.
The Hornets came into the game on the back of a comfortable 4-1 win against Preston on Saturday but struggled to create many chances.
