Speaking ahead of kick-off, Arsene Wenger has promised his side will be at the races from the first whistle.
"We go and we know its of course a very important game for us. We go with a positive attitude and try to win the game.
"I would rather say its a want win game. I said we had a bad start in the first game... we exposed ourselves.
"This time it is important we start stronger, more on the front foot than we did in the first game and the first goal will be important."
Arsenal's two most impressive recent Champions League wins have come from early goals, the 2-0 home win over Napoli, and the 2-0 away win against Bayern Munich.
It is no surprise Wenger is looking to repeat the recipe of that success.
Can Arsenal get the fast start they want?
