Watford asked the Premier League for that game to be postponed but will have enough players returning from isolation to fulfil the fixture against the Hammers.
The game will be the last of what has been a memorable 2021 for David Moyes’ side, who qualified for Europe with their sixth-placed finish last season and are already looking forward to the knockout stages of the Europa League in the New Year.
