BBC Sport football expert Chris Sutton has made his predictions for all 32 FA Cup third round games and given his verdict on who will make it into round four.
For this week’s matches he is up against actor and musician Billy Bob Thornton, who is a Liverpool fan.
Sutton’s prediction: 3-1
Fulham boss Marco Silva left Watford under a bit of a cloud in 2018, so it will be interesting to see what sort of reception he gets from their travelling fans.
Watford had been going pretty well under Tom Cleverley but three successive defeats have halted their progress a bit.
Fulham have had a great season so far, and they have a lovely balance about the way they play.
It would be great for them to have a cup run to go with their impressive league form, and hopefully Silva will be thinking that they should have a real go at the FA Cup, because they can beat anyone on their day.
As long as they go full strength, or close enough to it, they should get through this tie. That’s my thinking for most Premier League sides facing lower league sides in the third round, but of course that is not always the case.
Thornton’s prediction: 2-0
