Arteta and the whole Arsenal squad including the managements and fans were very serious about the Premier League title towards this end of the season. The lose against Aston Villa is the main cause of this debate of who should win within Arsenal and Manchester City, because with this performance and serious Arsenal have this season, going without a single trophy will be painful because they spent a lot to build the team and are in the right position to compete for the title. If Manchester City win all their remaining matches, there is no more hope for Arsenal.
But Arsenal are much better in the current position because they have been able to compete even with the fight for the Premier League trophy, we know Man City has been in great form for several seasons as well as the titles won with Pep Guardiola, therefore Arteta will not easily take it from Pep, this all needs a strong process and alliance.
Not that there is no hope it's just that it's in the hands of Man City and it's true what the comment above says, we have to wait for that result even though I don't think Man City will lose.
Something great has been achieved by Arteta with Arsenal now just waiting for the moment where they continue to improve their performance must be above Man City.
In last two seasons, things were really at the top while we are having them competitive for the title, but sadly things have never been favourable for them while they have good chance for the win but as they are playing and having experience and quality we can expect them for having another good season is waiting for them, and we can expect they could be leading contender for the title because now they are having their best strategy which was needed for the years.
Current season now all depend on Manchester City how they perform into their last 4 games because they are having good advantage due to bad performance of the Liverpool and Arsenal which lost their games on wrong time which was beneficial for the Manchester City to have another title as gift from these two clubs.
