Arsenal have managed to play consistently in the last two seasons. This shows that Arteta has succeeded in building a solid squad. Arsenal has a big chance to win the EPL next season. They seem to have been unlucky in the last two seasons. I'm not saying Arsenal are inconsistent because of the fact that they don't have much of a points difference from Manchester City. They were just unlucky when they got bad results in several important matches at the end of the season.
Arsenal has improved under Arteta but despite being good in the premier league, they have not been able to play very well in the champions league. Their participation is now looking like a waste of their time because they do not look like they can win the champions league. When giants like Real Madrid and Manchester city are competing for the title, Arsenal are looking like a team that is there only to fill up the teams that has to qualify for the champions league to start. I do not think they can win it this year either. When Arsenal play in the champions league it always fell like they are only qualifying from the premier league that others teams are not playing at their best and not because Arsenal were the better team because they do not show any signs that they deserve to be playing in the champions league.
