What is the difference now between Arsenal, Barcelona and Real Madrid? They're not in the same group are they?
You think of something that hasn't happened yet they are now in the group stage and Arsenal losing 1x is not a bad thing, I believe they can qualify for the Gunners not to worry Arteta's games and strategies are always interesting.
Don't doubt Arsenal now they look ferocious, even if Real Madrid meet later I have no doubt that Arsenal can win, anything can happen - so I don't think about how Arsenal are now because being in the group now they are not so worried.
Arsenal's stats are much better now, they have a lot of confidence.
Arsenal cannot be underestimated after successfully overthrowing the defending EPL champions and defending UCL champions Man City, Arteta now has the depth of a squad capable of conquering any challenge in various competitions. Even though we know their defeat against Lens was surprising, I agree with you that Arsenal can progress from the group phase this time. With their reputation this season, Arteta squad does have high self-confidence, they just need to improve their mentality to face big clubs in the next round.
The opportunity to meet Real Madrid or other big clubs is very open because they are not in the same group, but I think if there was another option, Arteta would prefer to avoid it. Not without reason, because the chance of beating a club as big as Real Madrid is very small, and the opposite could possibly happen. Beating Madrid is not enough with squad depth, an unbeaten record in the EPL League, or success in beating Man City, it cannot be used as a benchmark for beating Madrid.
