Arsenal failed last season because they didn't have a good mentality when under pressure from Manchester City. This season Arsenal and Tottenham are on a good track to fight for the title, but don't forget that the Premier League still has a long way to go so you shouldn't ignore Manchester City and Liverpool.
I put a lot of trust in the possibility of Manchester City being able to defend its title this season, but if Manchester City fails then I hope Arsenal will win it. However, everything is still too early to say because the Premier League still has a very long way to go.
There's more players interested in EPL title this season. We know the essential teams that would make it up for top four, the ones that would settle for other positions and the worst ones that would become relegated from the league due to the act of incapable strength to match up. Arsenal failed last season, they really got motivated by their extreme results by ending second and qualifying for UEFA Champions League. The gunners have keep up with the outstanding performance this new season, alot of mistakes will go on if what happen last time repeat itself, simply referring to injuries that affected them during the end period of EPL.
