Arsenal boss Arsene Wenger has heralded Bayern Munich as the "best in the world" ahead of their clash in the Champions League.
The Gunners are in dire need of a victory over the German side following back-to-back defeats in their opening matches in Group F to Dinamo Zagreb and Olympiacos.
However, Wenger has conceded that his side face a massive challenge to get their campaign back on track against Pep Guardiola's men.
Wenger told the club's official website: "[They are the] best in the world. [But] there is no team without weaknesses. If you ask me to come out with them then I would not especially do that but there is no team without weaknesses.
"What we want is to win the game. We want to defend well, attack well and score the first goal - that is massively important in the big games.
"You can never promise you will score three goals in 20 minutes [like against Manchester United] because that would be absolutely crazy. What we can do is start in a strong way and that is what we will try to do."
Arsenal have been eliminated by Bayern at the last-16 stage of the competition twice in the past four years.
