Watford will host sister club Udinese in a pre-season friendly a week before the new Football League season commences.
The Hornets will welcome Serie A side Udinese to Vicarage Road on Saturday, August 2, with kick-off at 3pm.
In recent years Watford have played their final pre-season fixture ahead of the new season at Vicarage Road and last year hosted fellow Pozzo-owned club Granada.
On Sunday, August 3, the club's annual open day will be held at Fullerians rugby club, with first-team players and staff in attendance to meet supporters.
Further details for the event and ticket prices for Udinese's visit will be announced in due course.
