Defensive duo remain sidelined for Watford
Watford must again do without defenders Sebastian Prodl (thigh) and Younes Kaboul (hamstring) for Saturday's Premier League match at Chelsea.
The Hornets have no fresh injury problems from last weekend's win over Arsenal, where captain Troy Deeney again started on the bench.
Midfielder Nathaniel Chalobah and defender Craig Cathcart both continue their recovery from knee problems, along with forwards Isaac Success and Mauro Zarate.
Provisional Squad: Gomes, Kabasele, Gray, Britos, Kiko, Cleverley, Holebas, Mariappa, Doucoure, Richarlison, Pereyra, Karnezis, Janmaat, Wague, Watson, Carrillo, Capoue, Deeney.
