Watford's Nathan Ake ineligible for Chelsea clash
Watford will have to make one change from the side which beat Liverpool last weekend when they head to Chelsea on Boxing Day.
Full-back Nathan Ake is ineligible to play at Stamford Bridge as he is on loan from the Blues, so Ikechi Anya could return to the side.
Defenders Tommie Hoban (groin) and Joel Ekstrand (knee) remain sidelined through injury.
Provisional squad: Gomes, Nyom, Cathcart, Britos, Prodl, Anya, Capoue, Jurado, Watson, Behrami, Deeney, Ighalo, Arlauskis, Guedioura, Abdi, Paredes, Diamanti, Oulare, Holebas.
