Man In The Middle: Andre Marriner
This will be Marriner's first Premier League game of the season, as he comes into this game on the back of taking the reins of recently relegated Hull City's away trip to Wolves in the Championship last weekend, with the game ending in a 1-1 draw, with only one player being sent into Marriner's book.
The man from the West Midlands had a fairly tranquil campaign last season, as in his thirty-three games he only dismissed two players, despite making one-hundred and twenty five bookings.
Interestingly, you'd have to go back to the 2009/10 Championship season to look at Marriner's last Watford game that he took charge of, as the Hornets were defeated on their home soil by Coventry City, where a single card wasn't produced.
Marriner will be assisted by both Scott Ledger and Darren Cann, with Bobby Madley being the fourth official.
