Arsene Wenger still harbours hope that Arsenal can top their Champions League group - but appreciates that it remains unlikely.
The Gunners advanced from the first group stage for the 15th successive year thanks to a 2-0 victory over Borussia Dortmund on Wednesday night.
The boss was pleased with the performance but they will need to win in Galatasaray on matchday six and hope that Dortmund are beaten at home by Anderlecht if they are to qualify as group winners.
"The victory makes you stronger. We analysed the Man United game very well and there were much more positives than negatives"
"It was a big game of a very, very high intensity and we had an outstanding performance," Wenger said. "It allows us to qualify for the 12th successive year for the last 16 in Europe. We’re [one of] the only teams who has done that and we are very proud of that consistency.
"It allows us to concentrate on our last game and focus on finishing top of the group. It looks very unlikely because Dortmund play at home against Anderlecht so they will have a good chance of winning the game.
"The victory makes you stronger. We analysed the Man United game very well and there were much more positives than negatives.
"Many football people made a very different analysis to press people. I think the Manchester United game was a very positive game where we could get a lot of belief, and the Dortmund game strengthened that belief."
Wenger hopes Arsenal can continue to build on recent performances against West Bromwich Albion on Saturday.
"[They are] a team that has a good technical level and maturity in their team,” he said. "They produce good quality going forward through the flanks. They get top-quality crosses in and they are very good on set pieces as well.
"All these things we want to control, but first [we want to] express the quality of our game and continue to have the same dynamic in our game."
