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.
Yeah Arteta just need to improve on the pattern he is using, though there is nothing wrong with his current patterns but since they have been using it for quite a while now but they still have not been able to win the premier League so he needs to improve or perhaps using another method will not be bad because it will certainly be very interesting seeing Arteta winning the premier League, though in as much as he has not been able to beat Pep Guardiola on the premier league trophy but I believe that Pep Guardiola is highly impressed with his level of coaching because it takes a good coaching skills to bring Arsenal to were they are on the premier League, so beating Manchester City will certainly happen when Pep Guardiola will no longer be coaching for Manchester City.
