After West Ham lost at Liverpool on Saturday and with Manchester United not in action until later on Sunday, Arsenal travel to Vicarage Road knowing a win will lift them in to the top four.
The Gunners are the team in form in the race for Champions League qualification and will be looking to extend their run of three straight wins on what could be a pivotal weekend in the Premier League.
Arsenal will feel this game represents an excellent chance to make inroads on fourth place, regardless of the fact they also have games in hand on the two teams directly above them.
For Watford and Roy Hodgson, the joy of a point at Old Trafford last week is tempered by the fact that they are three points from safety and have won only once this year.
