Man In The Middle: Anthony Taylor
This will be Taylor's seventh game this season, having already controlled six games, five from the Premier League, one from the Community Shield clash between Arsenal and Chelsea.
Notably to tomorrow's game, the majority of Premier League games that Taylor has took charge of this season have been televised.
He has handed out twenty yellow cards in his six games, and one red card, which came in unbeaten Leicester's win over West Ham, second game in of the campaign.
The last game he took charge of was Liverpool's one pointer at home to Norwich, last weekend, where Taylor dished out three yellow cards.
A lot a has changed since the man from Cheshire last took charge of a Watford game, turning the clock back to the Hornets' home draw against Norwich, back in the 2010-11 Championship season, where he cautioned four players, on the day.
