Watford are on the brink of signing Younes Kaboul and Roberto Pereyra but they will not be available to face Chelsea.
Brice Dja Djedje and Isaac Success remain sidelined, while Ben Watson is suspended after being sent off 12 minutes after coming on at Southampton.
Chelsea have no fresh injury concerns and could be unchanged from the side that beat West Ham on Monday.

MOTD COMMENTATOR’S NOTES
Mark Scott: “When thoughts turned to the managerial duels this season that have a bit of added spice, this one might have slipped under the radar a little.
“Walter Mazzarri and Antonio Conte fell out during their time coaching Napoli and Juventus respectively because, so the story goes, Conte felt Mazzarri had suggested he’d ‘copied’ Napoli’s formation.
“The Watford boss insisted his comments had been misunderstood, but formations remain a hot topic for both managers.
“Watford seem to have adapted well to Mazzarri’s preferred 3-5-2 line-up, putting in a solid showing at Southampton.
“Conte’s focus on overloading out wide against West Ham allowed Eden Hazard to deliver a performance much more in keeping with his fine form of two seasons ago.”
WHAT THE MANAGERS SAY
Chelsea head coach Antonio Conte on his relationship with Walter Mazzarri: “I saw (Mazzarri) in the managers’ meeting. I spoke with him about this new experience, this is a great challenge also for him.
“When we were in Italy and we fought for the title, Juventus against Napoli, yeah (there was a fall-out), but when you stay up and you are fighting for the title everyone fights for their club.
“But the relationship is very normal, I have great respect for him and his work. I think he’s a good manager.”
I am still waiting to see exactly what Hornets boss Walter Mazzarri’s philosophy will be in the Premier League, but I think Chelsea will have too much quality for them.
