The Blues took part in a thrilling 3-3 Champions League draw at home to Roma last night, but the point didn't come without a cost.
David Luiz and Tiemoue Bakayoko both sustained injury problems during the game - and with N'Golo Kante, Victor Moses and Danny Drinkwater already crocked, Antonio Conte faces some tough decisions.
Star striker Alvaro Morata is back in action though, and he started in last night's draw, so at least things are looking up at the top end of the pitch.
Watford are in excellent form and have already beaten Arsenal and drawn with Liverpool this season.
