Fresh from their first home win of the season, Norwich City are looking for back-to-back league victories for the first time since February as they head to Vicarage Road (12:30 GMT).
Watford are unbeaten in their past six league games at home.
Watford lost this exact fixture 1-0 in February last season, last losing consecutive home league games against Norwich in November 1995.
None of the past 16 league games between Watford (W9) and Norwich (W7) have been drawn, with the Canaries winning each of the past three.
Watford have lost just one of their past 10 home league games (W5 D4) and are unbeaten in six since a 1-0 loss against Blackburn in September (W4 D2).
