Arsenal last season was not bad they only lost a few times to be left behind by Man City while Liverpool in the previous season slumped because of many injured players while the current season has risen again only Man City remains stable every season.
I think Arteta explored the problem last season until now will not happen where his team misses towards the end of the season only need to survive even though it is not easy but we see Arsenal who are quite solid in their game.
Man City and Liverpool will continue to fight fierce competition, they will play very carefully, about Klopp leaving we don't know how Liverpool will choose a new coach later.
Arsenal performance keep improving in this season regarding inconsistent and loss many crucial matches in last season, Arteta success build up with the mentality winning on every crucial match face by Arsenal exactly success hold draw Manchester City on game week 29 and Arsenal won two consecutives matches in last two games.
Learned more from fatal mistake did by Arsenal last season and make Arteta success give the first standings awhile for Arsenal and left 7 matches later to make him self become history as manager success winning Premier League tittle after last twenty years ago for Arsenal become the winner. Still has many difficult left match but Arsenal need confidence and winning mentality to secure three points at all matches left, for next match must win against Aston Villa and defend the first place from Liverpool or Manchester City.
