Given all of the remonstrations, I thought it interesting to find that Arsenal leads the league in penalty goals scored with 6 so far this season. The next closest team has 3. Last season, the league leader, Manchester City, scored 9 penalties and Arsenal only scored 3. Since VAR was introduced, the highest ever total for penalties scored in a season has been 10. Conversely, Arsenal led the league in open play goals scored last season jointly with Manchester City, whereas so far this season, they are mid-table in open play goals scored and mid-table in shots taken per game. The fluidity of play and unpredictability does seem to be lacking so far.
I think the defensive improvement over last season has been overstated a bit. They have only conceded one fewer goal in the league so far this season relative to the same point last season. It's not apples to apples, because Arsenal have probably had a tougher schedule to start this season, but it's something to watch for. A huge contributing factor to the defensive drop-off last season was the injuries to Saliba and Tomiyasu, leaving Arsenal reliant on Holding and Zinchenko. Their goals conceded per game ballooned after that happened. Now that Saliba and Tomiyasu are available again, the defense looks solid again. The additional defensive reinforcement from the midfield only appears marginal, at best, and I'm not sure it offsets the loss in creativity and fluidity. Thus far they are conceding slightly fewer shots per game than last season, but the statistics from last season also include that long stretch when Saliba and Tomiyasu were unavailable. I think the defense is slightly better this season, but I do not think it is that drastic of an improvement over the defense when Saliba and Tomiyasu were available last season.
