Watford: The 'Hornets' have had an incredible start to the season, winning all of their three opening games convincingly and seeing the likes of Roberto Pereyra and Will Hughes hit excellent form.
Tom Celverley is a long-term injury concern, but Gerard Deulofeu could make an appearance after an injury lay-off, but is likely to be on the bench if he features at all in this one.
Tottenham: 'Spurs' have had an equally impressive start to the Premier League, with Lucas Moura impressing in particular with two goals on Monday to help down Man Utd 3-0 at Old Trafford, while Harry Kane has also scored in his last two games.
The big injury news is that Hugo Lloris will not feature in goal due to a thigh injury so Michel Vorm will come in to the team, while Moussa Sissoko is also out with a hamstring issue.
Watford manager Javi Gracia on building on his teams good performances this season:
"We've played against very good teams and for me Crystal Palace, Burnley and Brighton were difficult games. I know Tottenham play in the Champions League and have very good players and a very good coach but it's no different for us.
"It's our mentality. We know they're very good players but in this case we are only focused on looking for a way to try to win."
Tottenham boss Muricio Pochettino on his opposite number's start to the campaign:
"They have very good players, and I know the manager very well, Javi Gracia is a very great coach, a fantastic coach and it is not a coincidence because they did a very good job last season and they started well this season and it is going to be tough to play against them.
"It will be a difficult game but an exciting game as we are both at the top of the table and surely it will be a fantastic game to see."
Prediction: 1-2
