Arsenal boss Mikel Arteta says they must keep their heads at Liverpool today.
The Gunners go to Liverpool as Premier League leaders.
Arteta said: "It [Anfield] is different, different like Old Trafford. Old Trafford has a beautiful atmosphere as well and something that historically is an unbelievable place to go.
"There are a few in this country. You have to go to these stadiums and you have to prove as a team what you are capable of. Sometimes when you don't feel at your best you feel that they are on top of you, and you cannot get out of that washing machine. You try to overcome those situations but that's learning - it happened once and it didn't happen again."
On avoiding such flare-ups, he added: "[Follow] the game-plan and everything that we discussed to try to be away from that game, and put on our washing machine that is very powerful. The emotional state is something that is crucial when you play against big opponents away."
