The Hornets defeated the Gunners in the FA Cup quarter-finals earlier this month, and they will once again travel to Emirates Stadium to face Arsenal in a league game on Saturday.
The Spanish defender told Arsenal Player: "We're coming off the back of two really good performances, the most recent of which we won.
"We know it's going to be difficult against Watford because we only played them recently and they knocked us out of the FA Cup, but we're hungry for revenge.
"It's a completely different competition. They're not fighting for big things so we need to show that we are. We need to show we're the home side and that we want to keep fighting for the league title.
"That's what we're going to do."
