Watford could visit Manchester City in the FA Cup for the second season running if Beppe Sannino's men win their third round replay against Bristol City.
The Hornets will face the Robins at Vicarage Road on Tuesday, January 14 following yesterday's 1-1 draw at Ashton Gate, with the winners meeting the victors of the replay between City and Blackburn Rovers.
They also drew 1-1 at Ewood Park after Alvaro Negredo's goal at the end of the first half was cancelled out by Scott Dann ten minutes after the restart.
Watford travelled to the Etihad Stadium in the third round last season but were beaten 3-0 through goals from Carlos Tevez, Gareth Barry and Marcos Lopes.
The fourth round ties will be played over the weekend of Saturday, January 25.
