The Gunners were two goals up after 30 minutes, but let their advantage slip coming away with a single point.
Although they occupied a commanding position, the Frenchman believes that there were many positives to take from the encounter:
“With all the stick we got after Saturday’s game, it was important to show a good response and I think we did that.” He told SkySports.
“It was a difficult game – a good one as well, both teams played very well.
“It was unfortunate that we conceded that goal before half-time, and in the last minute we had the chance for 3-2, but overall I think a draw was fair.
“At 2-0 you have not won the game in the Champions League.
“German teams have physical quality and technical quality and they never give up, so I never felt the game was over.”
Theo Walcott missed a good chance late on which midfielder Mikel Arteta admitted was a big moment in the game:
“Considering we were 2-0 up, it can’t be good for us. We had the last chance too with Theo.
“We were unlucky to concede just before half-time. It was a completely different game, but that happened. But this is not an easy place to come. We’ll take the point.”
Arsenal took the lead through Walcott after quarter-of-an-hour before Oliver Giroud doubled the advantage with a fine header on the 26 minute mark.
Klaas-Jan Huntelaar’s clinical strike made it 2-1 on the stroke of half-time and Peruvian winger Jefferson Farfan completed the comeback with a deflected effort after 67 minutes.
