Arsenal have maintained their place at the top of Group F in a goalless draw against Marseille at the Emirates.
The home side struck more shots on target in the first half, while the only real threat to Wojciech Szczesny came through Mathieu Valbuena in the 21st minute.
Manager Arsene Wenger opted to bring Robin van Persie off the bench just after the hour mark but the skipper, who achieved a hat-trick in the weekend's clash with Chelsea, failed to break the deadlock.
Three points would have guaranteed the Gunners a place in the last 16. They will next face Borussia Dortmund on Wednesday, November 23.
