Maybe 3rd time it will be a lucky charm for Arsenal ? they surely deserve to win EPL but on the same time , no year resembles the previous one and the players will have to understand they actually have to be more consistent , more prepared , more trained in all aspects. City most likely will have another great run towards the title and I don't see neither Liverpool , United or Chelsea to put problems but I do see Arsenal once again fighting for the trophy and hopefully achieve it. 
Arteta has managed to build the Arsenal squad quite well so far but consistency is still a problem that they must fix next season, two consecutive seasons Arsenal were able to compete for the title and even they are getting closer to the championship trophy, before finally losing points in important matches actually make them have to give up the opportunity to be championship,in the last two seasons, Arteta will of course build their squad better next season and of course at this time Arsenal must be able to improve their mentality and also their consistency next season in order to break Manchester City dominance.Arsenal failed to win twice when they were very close to the trophy, so it is time for Arteta to analyse and of course strengthen some lines that are still too weak to compete, besides that Arsenal next season will again face a tight schedule and I hope Arsenal can be consistent in every game they have to be able to break Manchester City dominance next season .
I also hope to see Arsenal win their first championship trophy after 22 years of title fasting.
