Arsene Wenger said Arsenal's performance against CSKA Moscow might have been their best in the Champions League in his time as manager.
Wenger felt there were many positives for his team
Arsenal missed a multitude of chances as the match finished goalless.
But afterwards Wenger said: "The team played exceptionally well - maybe the best Champions League game since I have been here.
"The team played very well but we did not take our chances early on and then there is big pressure on the next one."
Arsenal now have a home game at the end of November against bottom-of-the-table Hamburg, who are without a point after losing 3-1 at home to Porto, Arsenal's final opponents in Group G.
The Gunners had 24 shots on goal and Tomas Rosicky was guilty of the most glaring miss - failing to put the ball into an empty net from three yards.
But numerous team-mates also spurned good chances as Arsenal missed the opportunity to move to the top of Group G.
"We should have won by five, six or even seven," said Wenger.
Normally, you win this sort of game 7-0
"People will feel frustrated by the result but for me it is the best in the Champions League we have played since I've been here.
"Normally, you win this sort of game 7-0 - or maybe 7-1 because CSKA had a chance as well but I still feel there is a lot of positives for the team.
"We were not guilty of trying to score the perfect goal this time.
"We dominated this Moscow team by miles and created clear-cut chances. There was a division of difference between the two teams but we have to take the result.
"Yet, I still feel that this team has great potential and it is how we mature in the coming months that will decide whether we win a trophy."
"It will be difficult but there are still so many positives for us to take from this performance. I am convinced one day we will play far less well than that and score four, five, six goals.
"We need to keep the belief. It is nothing to do with the new pitch. It is much more simple than that. We need to put the ball in the net.
"But our crowd were great tonight. It was a great crowd, a great performance and a bad result."
