There are some weird reactions on here, I'd rather be in Arteta's shoes compared to Erik's that's for certain. Last season the Arsenal team set a benchmark and realistically lost the title due to inexperience and not having winners in the team to set the expectations.
You've won 7 and only lost 1 game this season, because it's early doors I understand some United fans thinking us being close is some achievement due to the abysmal performances but if you expand those games to 22 instead of 11, the points gap would be more significant as a poster highlighted above.
No team has really played exceptionally, so this season could be one where there's less separation but City typically get their stride in the new year as we've been here before. The difference with United is Arsenal aren't playing great but there's evidence as of last season to show they can. We under Erik haven't had the luxury of playing well consistently, so why there's hope for things to improve there's not much evidence to support that desire.
