After getting pretty good achievements last season and also having a good chance to become a champion, I think Arsenal will definitely set their target to win this season. For that they must have good preparation and keep trying to look even better. I guess the title race will be fierce again because Man City, Liverpool, Chelsea and Man United will also do the same (as Arsenal did) for that title fight.
Last season was indeed one of the best seasons for Arsenal, how could they get up and at least manage to put pressure on Manchester City to fight for the EPL title. It was a great achievement in one season and in the end Arsenal also got a place in the champions league even though they failed to win the EPL.
Mikel Arteta certainly doesn't want to get the same results for next season and become runner up again, this time he will definitely be more serious about bringing his players for totality in every game so they can get an additional three points. Very fierce competition will occur in the next season and some of the clubs that you have mentioned above deserve to be able to compete again for the EPL title.
