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. 
Maybe and hopefully.
Arsenal have been getting close to the Premier League title for two seasons but still there isn't a happy ending. Indeed, they totally deserve it especially after the performance they had this season.Arteta is a wonderful manager. He has already proven that. It isn't easy to compete this hard against Guardiola's Manchester City with such a young team. I really hope to see Arsenal as the champions next season to finish this 20-year longing. They are improving their statistics every season if you have noticed. They are more productive and much better at defending at the same time. It is time to be crowned as the winner of the Premier League.
Failed 2 seasons in a row and only always finished runner up, there should be a conclusion that can be used as a lesson for Arsenal, and it's appropriate for Arsenal to conduct an evaluation because that way they can make more thorough preparations for next season.
What I see is Arsenal is lacking a goalscorer and the transfer window should be an opportunity for them to overcome that problem. Apart from that, Arsenal hasn't won the Premier League trophy for a long time and I think that can be a motivation and at the same time, it could have been a burden that might affect their mentality (it's something that Arteta should pay attention to).
