Arsenal are slowly starting to improve their performance and consistency of play each season, so it can be said that Arsenal prospects in the future will be even brighter, now we can compare Arsenal this season and last season if there is a significant improvement in their play and consistency in the Arsenal squad in the competition for champions, Arteta now only needs to improve the winning mentality that their young squad has and I think next season with several additional players in the striker position and also back up wings, it is certain that Arsenal will again be able to compete to become title contender.
What you say is true because so far to build a winning team of course requires a long process, Wenger has built a strong foundation at Arsenal so that when Arteta comes of course he only needs to build his mentality and also modify his style of play inherited by Wenger during his time at Arsenal, for now I think Arteta will be retained by Arsenal even though they failed to win, because we can see that Arsenal in the last few seasons can compete again as a challenger for the English League title.
We can see the comparative statistics of last season and this season, but the progress in terms of numbers is very slight, namely in terms of total goals scored, conceded and final points. Last season, Arsenal was able to collect 84 points from 38 matches played in W26, D6 and L6. Meanwhile this season there is 1 match remaining and the results will make a significant difference, but in the meantime, from a total of 37 matches that have been played Arsenal have been able to collect 86 points, 27 wins, 5 losses and 5 draws with a total of 89 goals scored.
With growth in a better direction, of course the opportunity next season to continue chasing Manchester City makes more sense. Maybe Arteta needs to replace some players who are rarely used, selling him is the best option to be able to find players he can rely on. If we pay attention, Arsenal has players whose role has never been seen at all this season, so rather than not making a contribution, it is better to sell them in the next transfer market.
