Arsenal have made a lot of changes this season, and they have also spent a lot of money on it, so it is very reasonable that they will be a tough opponent for Liverpool, as they also have the same target as Liverpool this season. I think both Liverpool and Arsenal were quite cautious in that match, and they seemed unwilling to make any mistakes that would cost them, therefore, the match looked boring (especially in the first half), and not many chances were created by either team.
That makes sense and that's why we only saw one goal in this match. Honestly, at first I thought both teams would play aggressively even scored 3-4 goals but unfortunately not and I lost the bet on both teams to score. Even though Arsenal lost today I don't think they lost their chance in the race I mean Arsenal are still candidates for the title yeah at least for 2nd or 3rd position, indeed, it is too early to predict because shifts can occur at any time but slowly the consistency can be seen.
By the way I highlighted the defense of each team and I see Chelsea as the most solid so far they only conceded 1 goal in 3 matches, Arsenal also have the same record but Chelsea are slightly better based on goal statistics. It must be admitted that a solid defense is one of the determining factors in the title race that's why I added Arsenal and Chelsea to the race list.
