Next season is the time for Arsenal to stand a d fight till the end so that Arteta can prove to Pep that he has improved very well and have become better, otherwise Arteta will still remain a boy to Pep if he cannot win the league in the third season after making good attempt in two consecutive seasons.
Arteta in the last two seasons has done quite a good job at Arsenal even though he has not been able to break Manchester City dominance so far, but even so, at least what Arsenal has done in the last two seasons is a warning to Guardiola if Manchester City could slip up next season If they don't immediately improve the quality of the squad they currently have, Arteta who was previously Guardiola student or assistant, will definitely continue to try his best to beat his teacher and show Guardiola that he is no longer worthy of being underestimated as a coach at this time.
I agree with you because Arteta has worked very hard for the club to grow but without defeating Pep Guardiola he has not really balance well, though Pep Guardiola thought him everything he knew about coaching but if Manchester City continues beaten them and taking there chances of becoming the premier League champions he will always be considered not enough to be compared with Pep Guardiola, however Arteta was almost certain of wining the premier League this season and prove to Pep Guardiola that he is also good but his boy wasn't good enough at the last part of the season, though in the case of next season I don't really know what will happen but the fact is that it will be very nice if Arteta will be victorious because there has been a lot of talk about him so next season would have been the time to prove himself.
Arteta just needs to continue to improve the composition of his current squad so that he will continue to be able to compete with Guardiola, Apart from that, currently Guardiola future at Manchester City is unclear after he only has one year remaining on his contract with Manchester City and that should be the last chance for Arteta to be able to show that he is able to break Manchester City positive trend next season, destroying Manchester City dominance is not an easy thing, especially since Manchester City and Guardiola have been supported by strong finances and but that should be a whip for Arsenal and other teams in the Premier League to be able to perform even better next season in order to break Manchester City current record of winning streak in the English league.
