The Gunners will face the Blues at the Emirates Stadium on Saturday with the local rivals only separated by goal difference in the Premier League table at the moment.
"It will make a difference, but at the same time you've got to keep a cool head and you can't let all of that cloud your judgement or get the better of you on the day," he told Arsenal Player.
"You know, if you go a goal up and the crowd starts getting right behind you it can push you on. At the same time, sometimes you might end up going a goal down and the crowd can show their frustration and you can't let that affect you too much because you've got to focus on getting the right result and keep plugging away.
"The crowd will be massive and I'm sure the atmosphere will be great. It always is for the big games and we've got to use that to our advantage.
"We need to get the right result so everyone leaving the Emirates happy."
