Chelsea boss Antonio Conte does not expect Arsenal to change their shape for Sunday’s London derby at Stamford Bridge.
The Gunners reverted from three at the back to a back four in their Europa League game against Cologne on Thursday.
However, asked if he believed they might do the same this weekend, Conte said: “I don’t think so. Don’t forget Arsenal always played with a back four and then last season they changed the system, but I think they won’t change against us.”
Conte confirmed that Eden Hazard is “almost 100% fit” following his recent ankle injury.
Hazard is in contention to start Sunday’s game and Conte says he will decide his team on Saturday.
The Italian said: “I have another another day to check the physical condition of all my players and then try to make the best decision.
“I have another day to reflect and then to make the best decision for Sunday.”
Meanwhile, recent signing Danny Drinkwater is expected to remain sidelined until next month with a calf problem.
