Both players missed the 1-1 draw against Brighton last weekend with Haller suffering from a swollen knee and Anderson suffering a thigh issue.
Highly reliable West Ham source ExWHUemployee was asked whether he had any news about the pair on Twitter on Wednesday night.
He replied that “both have been in training and both due to figure against Watford”.
Yep both have been in training and both due to figure against Watford https://t.co/wq6GFtu4uX

Watford are rock bottom of the league and a visit to Vicarage Park on Saturday is the perfect opportunity for Manuel Pellegrini to get his first three points of the season. The return of Anderson and Haller will be a boost but it’s not clear yet whether they’ll start or be used from the bench. However, ExWHUemployee does say that both players will figure and they’ve been training this week so it looks positive. Their replacements did okay against Brighton without doing enough to keep the pair out of the side. Pablo Fornals was awarded a rating of 6.3 by WhoScored, the second-lowest on the West Ham team after Jack Wilshere. He had a bright first-half but faded after the break. If Anderson is fit then we expect to see him on the left with Manuel Lanzini moved in-field. Javier Hernandez was given a rating of 6.9, behind Robert Snodgrass and Lanzini in the West Ham attack. He was anonymous in the first-half of the game but scored with his one clear chance after the break. Service was the big problem for him and that will be the same if Haller comes back into the side from the start.
