Biggest Storyline: Must-Win Scenario
Arsenal pulled out an injury time goal against the French side just a few days ago to earn a 1-0 win.
Substitute Aaron Ramsey rescued the Gunners and put them squarely in control of the their own destiny.
Marseille has to play for a win or they'll leave their destiny in the hands of someone else. Even a draw gives Arsenal a one-point advantage and should they both win, the Gunners will move on.
Unless Marseille thinks Olympiakos or Borussia Dortmund can at least square away a draw with Arsenal they have to play for a win.
Arsenal Player to Watch: Robin Van Persie
The Dutch international star has taken over the captain duties for this club. They'll need exactly that in this match.
They need to continue playing the same way they have been and getting the ball to their captain is a big part of that.
Marseille Player to Watch: Loic Remy
The 24-year-old Frenchman has four goals in 11 league games.
He also has 36 shots.
Remy gets a lot of opportunities and isn't shy about acting on them.
The French side is going to have to score goals if they want to beat the English powers, so look for him to be around the ball a lot.
What They're Saying
The Gunners have a match against fellow Londoners Chelsea on Oct. 29 at Stamford Bridge.
They hope they can use that match and take control of their Premier League seasons they have in the Champions League.
After stealing a game in Marseille on injury time they can only hope to replicate the outcome at the Emirates.
Winger Theo Walcott had this to say about it (via Goal.com):
In the Champions League, you want to at least draw the away games, but we managed to sneak it in the end," he said. "We were very solid at the back and we need to do that more often - dig deep and win games 1-0. It was nice to see that in Marseille.
Prediction: Arsenal 1, Marseille 1
