While Arsenal need just one point from two games to ensure progression to the Champions League knockout stage, Tuesday night's opponents Standard Liege are battling with Olympiacos for second place.
The Greeks hold a two-point advantage and travel to AZ Alkmaar knowing a win would seal their place in the last 16 if Standard don't defeat Arsenal.
To find out a little more about just how important this game is to the Belgian champions, we spoke to Het Laatste Nieuws reporter Kristof Terreur.
IMPRESSIONS OF ARSENAL
Everyone is looking forward to the trip. Everyone says Arsenal is a team who plays perhaps the most beautiful football in Europe at the moment; everyone in Belgium looks forward to watching Arsenal play when they are on TV. They were very disappointed with the result in Liege. If you are leading 2-0 after five minutes you would think it would be easy to win. They have to take at least one point on Tuesday because Olympiacos are already two points ahead [in second place] and if they get three points against AZ, Standard will be out unless they defeat Arsenal. But it's not mission impossible for them.
CHAMPIONS LEAGUE FEVER
We have a new league format in Belgium where we have play-offs to determine the champions. They must only finish sixth to be in the play-offs and for the play-offs the points will be halved - so if they are 10 points behind the leaders, it would be reduced to five points. This means that Standard can really focus on the Champions League.
CAUSE FOR CONCERN
They have lots of injuries and they will play with a very young squad. Milan Jovanovic [Standard's top-scorer with nine goals in 14 league games] has not travelled with the squad. Steven Defour and Igor De Camargo are not there either so they have some key players missing.
To not have Jovanovic is a massive blow. He told me yesterday that Arsenal is the most important game of the year and he is disappointed not to be there. It is not a major injury but they do not want to risk him.
THE ONE TO WATCH
Axel Witsel is one of the young stars of Belgian football. He is getting better every week. In the last Champions League game against Olympiacos he played to a good level and in Belgium he has been going well too. Witsel's favourite club is Arsenal; he went there last year to visit the stadium and watch the team play. He is a huge Arsenal fan.
