It's a big game for the Arsenal this evening.
Anderlecht, are strong opponents and not to be taken lightly.
The last time the sides played, the Gunners came from behind to score a dramatic late victory, two goals in the dying minutes swung it for them and they ran out 2-1 winners.
Assuming Wenger's boys win, and Turkish champions Galatasaray lose, then Arsenal are into the last 16 of the Champions League.
Fans can't really argue with the team's record in Europe, when it comes to qualification at least. This the 17th consecutive year that they've made the groups.
Opinions on how the team are doing this season vary, some feel they should be winning more in the League and not drawing so many games.
But, the shining star of the campaign so far has been Alexis Sanchez. Three goals in the last five games in the League for the club, keeping him fit will be key for the team's success in domestically and in Europe.
London Live's Gavin Ramjaun thinks Arsenal have a good chance to progress far in Europe this season, as they have a lot of players to come back from injury. But, plenty will disagree.
