Arsenal made the same mistake twice, hopefully they won't make the same mistake a third time and the third time they will definitely be able to take the result in their favour.
Mistake that happened a second time is not a mistake, they are just not able to win and if only means they are not capable of beating Manchester City.
They can try again next season but it will still be difficult if they don’t improve their squad. Firstly i think they need a better striker, they should stop deceiving themselves that Havertz will solve their goal scoring issues. Havertz is not a natural striker so need to get a natural striker that can win matches for them singlehandedly. With Haaland Manchester City don’t seem to have a striker problem anymore and his goals go a long way for the team.
Repeated mistakes, even when they have a chance to stay away they also fail. If you remember when Man City also lost points from several matches, Arsenal was unable to maximize the match with a victory.
Arsenal need to able to win matches that matters of they ever want to win the title, they could have won the league had it been they won the game against Aston Villa, a very crucial match after Manchester City had dropped points and winning could have changed the whole story but they went on to lose at home to Aston Villa that was when i knew they wouldn’t win the title.
