Nah, they'll fuck themselves over like they always do.
This stuff about Arsenal 'fucking themselves over' is just a lazy narrative. No club has lazy narratives applied to them more than Arsenal do. Same as stuff about them trying to 'walk the ball in' despite scoring all kinds of goals or being 'soft at the back' despite an excellent defensive record for a while.
The fact is in the past they never had the squad capable of competing for the title and lacked the quality and depth of Man City/Chelsea/Man Utd, simple as that. Now they do so long as they don't all end up on the treatment table.
