Winning the Premier League was never easy for any team and they were always having a close race to win the title even until the last moment of the season. I think until the last moment there we can't say which team is going to win, for example in the last season we had a bad performance from Manchester City at the start but time after time they made progress and Arsenal lost their place. There is the chance to see the same thing in this season However this time Liverpool also has the chance for it.
What we can say is that the competition will continue until the end of the season, and Arsenal, Liverpool and Manchester City will continue to be in the race for the trophy this season. The challenges faced by the three teams will be different from last season, where in my opinion common factors such as player injuries and a busy match schedule can affect their chances of realizing their ambitions. If Liverpool are lucky then it will be a beautiful farewell to Jurgen Klopp, if Arsenal are lucky then their wait of more than two decades has now been fulfilled, while if Manchester City can win the trophy again then the Premier League will be easy for them.
However, Arsenal now has its own charm, where in my opinion they have developed to be better prepared for any challenge and pressure. That doesn't mean that bitter history like last season won't be repeated, but it looks like they now look more ready to become champions. Arteta has managed to build a squad very well, having balance in every line, something they didn't have last season. So therefore, if they fail again, it means Arsenal don't have a problem with squad depth, but I think they have a problem with mentality.
