Wenger was delighted with the resilience his side showed, and believes it augers well for the rest of the campaign.
"You could see that defensively we are getting better as a unit, as a team," he told Arsenal Player. "That is one of the positives of the day.
"We won the game in the end because we really wanted the points but we were hanging on a bit in the last 30 minutes. I am very happy that we made it in the end but we were on the ropes a bit.
"We made a demonstration offensively against Reading [when we won 5-2], but here it was more of a demonstration of defensive efficiency. I hope in the next game that we can produce the two together."
