While the home side have dropped two points in their opening three fixtures, Forest are currently on a 100% record and sit at the top of the table, with Watford residing below.
Gianfranco Zola's team can leapfrog Sunday's opponents into top spot if they grab all three points, and they are expected to try with the help of defenders Marco Cassetti and Joel Ekstrand, who are both fit for the match.
Cassetti was absent from Watford's 3-3 draw with Reading due to a foot injury, while Ekstrand suffered an ankle problem during the first half.
