Chelsea boss Thomas Tuchel believes Arsenal's fans won't be a factor on Sunday.
It's been claimed Arsenal fans are already unhappy with their players going into the game.
Tuchel said, "We had a pre-season match where we could see the energy that this derby can produce in this stadium. It's always a tough one, it's always a tight one.
"They had a rough start and from their perspective it can be a help that a big rival from within the city arrives now and it can create a situation where they stick together and try to win their crowd over with a strong performance so we should be absolutely prepared for the best Arsenal possible.
"At the same time, we need to do what we need to do, push the standards to the limits on Sunday and let's see where our limit is and look for an intense game. Look for rhythm and a confident game on and off the ball. Anything else but a tough game would be a big surprise."
