Yesterday's defeat could not be judged as a failure but the defeat against Liverpool reduced Arsenal's chances of trying to win the title this season.
Arsenal's attack line performance is good but like can't take advantage of good opportunities against equivalent clubs like Liverpool.
Mikel Arteta must give a little change to the attack line if it does have the motivation to try to win the title this season.
Yes they're currently trailing Liverpool, but that doesn't mean they're doomed, as there are still 35 games remaining. What's clear is that Arsenal must be much better than last season. They must be consistent and avoid losing their rhythm midway through the season as they have done previously. Likewise Gyokeres must perform consistently as he is the spearhead and key to Arsenal title hopes.
It's strange to judge a team that's only played three weeks, or just three games, with less than satisfactory results or a narrow points gap in the table, and immediately assume they're bad or something, especially a top-flight team.
This is just the beginning, and anything can happen and change, because no manager wants their team to consistently suffer from poor results, and they will continue to work on improving their team's performance and finding ways to achieve better results in future matches.
And I think Arsenal are playing well, having won two of their three Premier League matches. Arsenal also played well against Liverpool at home, and their 1-0 loss to Liverpool showed Arsenal's defense is quite good. It's just that Liverpool were luckier and slightly better than Arsenal, and Mikel Arteta needs to address this by strengthening his defense and sharpening his attack. And when they beat Leeds 5-0, for example, it showed that Arsenal are playing well, but they just need to improve their existing form to be consistent against the big teams.
