Arsenal boss Mikel Arteta says the home support will be important today against Liverpool.
Arteta says they need the home support to be up for the clash.
He said: I want our fans to play every single ball with us - so we create a really vibrant, positive atmosphere.
In this way, we're going to make it really, really difficult for Liverpool. I'm convinced that's going to be the case. The team always have to give the first step and then the crowd react to that.
But there are special moments, and Sunday is definitely one, when I think it has to be them (the fans) at the beginning, from the whistle. That's the way you approach the game, the way you sit in the stand, the way you communicate with the person next to you.
You have to create the atmosphere and I'm confident that's going to happen."
