Chelsea travel to the Emirates Stadium in great form, coming off a run of only one loss in their last 13 games - with ten wins along the way. The champions destroyed Stoke 5-0 in their last game of 2017, and will be looking to pick up right where they left off on Saturday.
Antonio Conte has no major injury concerns ahead of Wednesday's London derby, and will be confident of getting a good result against their city rivals.
Here's the team Antonio Conte could pick for the trip to north London:
Thibaut Courtois will undoubtedly keep his place in goal.
Andreas Christensen missed the Boxing Day match due to illness, and recovered to be an unused substitute against Stoke three days later. The Dane should return at the heart of the defence, replacing captain Gary Cahill.
Cesar Azpilicueta will play on the right of the three, and Antonio Rudiger could be called upon, fresh off his goal against the Potters on Saturday.
With Cesc Fabregas an unused substitute in the win over Stoke, the former Arsenal man will return to try and unlock his former club's defence. N'Golo Kante should play alongside him.
The usual wing-back pairing of Victor Moses and Marcos Alonso should continue on the flanks, despite Davide Zappacosta pushing for a starting place after his goal off the bench at the weekend.
Willian was the star of the show against Stoke, with a goal and two assists, and his good form should earn him a place in the starting XI ahead of Pedro. Alvaro Morata has ten Premier League goals so far this season, and will look to add to that tally against the north London club.
Rested at the weekend, Eden Hazard should be fresh and ready to cause problems to Arsenal's injury-hit defence.
