If they want to win the Premier League title, they have to keep performing consistently. There is no alternative. If you can't keep performing consistently, you won't be able to win the Premier League title. Because every season, 2/3 teams fight for the Premier League title.
In the last two seasons, we have seen Arsenal's inconsistent performance towards the end of the season, and Manchester City won the title in the end. We have seen Arsenal's inconsistent performance at the beginning of this season. And Arsenal is now 9 points behind Liverpool. This season, it will not be possible for Arsenal to compete for the title.
Yea, you are very much correct on this bro, the high level of inconsistency is the major difference between arsenal and Manchester city side that has won the English premier league title in the past four seasons if am not mistaken, because the quality is also there in these arsenal team, but they are just too inconsistent to compete.
Just as you rightfully pointed out, they became inconsistent when it really matters, towards the end of the season when everyone is giving their best hoping to finish strong and win something, but in the case of arsenal, they will be inconsistent during that period, so as it stands now, if they really want to win the premier league now or in the future, they just have to start ranking up the winnings and be as consistent as much as possible, and be hoping that Liverpool will drop point along the line, because right now, they are actually in a tight Conner due to their inconsistency.
