I feel like you completely ignored my entire post, especially the bolded, so I'm just going to repost my quote again
People keep seeing the name Arsenal and ignoring the massive problems that club and side had. He took over midseason, had he took over from the start then his points ratio would have got them 6th place (they were lower in the table and in freefall when he took over) and he also went and won the FA cup. In his first full season he bought in Partey for big money, but he missed large parts of the season, Gabriel was also bought in for about 20m and he's been a great signing. There was also Mari for peanuts. He was still using a squad that wasn't his and had major issues. This is his second full season, and he's been backed in the transfer market. He's purchased a bunch of young players for big money, ones specifically bought in to play the football he wants. After a horror start (in which there were extenuating circumstances but let's not get into that) he's got his team playing with more confidence, certainly with more tactical confidence. Yes in his first full season he finished 8th, 5 points off 4th. This is his second season and it'll be interesting to see how they do. I honestly don't understand what supporters expected.
About Emery, he did an ok job. He finished 5th which was great, but they were lucky to achieve that position, both by the statistics and the general level of their play. His transfers in his first season were all failures, and in his second season he went and spent 75m on fecking pepe. The wheels came off a few months into his second season, and they were in the bottom half of the table with like 1 win in 11. So I'm not really sure what you're getting at here.
This summer is the first time he's been able to spend. He has spent big this summer (very big for Arsenal) but it still comes to about 220m, Ole has spent 410m, he also inherited a better side.
I don't want to make this a Ole vs Arteta, I'm solely pointing out the disparity in the jobs they took over. For some reason many in this thread seem to think that they both started on the same starting line.
As I said, come back to me in May and we will see. Maybe he'll get top 5, maybe he'll be 8th again.
