Wenger was the best thing to ever happen to this club, he carried us to the top 4 with a very poor squad and no investment for a decade. Finishing in the top 4 with players like Bendtner, Chamakh, Djourou, Senderos, Gervinho, Andre Santos and Squillaci as regular starters is astonishing, Wenger is an absolute footballing visionary who always got the absolute best out of all his players. During his last 6 years, he overachieved considering the squad at his disposal. His fast paced, offensive system with passing triangles is something our squad would thrive under today. If anything, todays struggles prove how much Wenger carried us.
Most of our struggles right now is because of Emerys brainwashing on the players, the confidence is shattered as a result of him not allowing the players any freedom on the pitch, always looking to adjust to the opponent. We don't have much of a tactical base to rely on, because Emery had no tactical system. It takes time to implement a new one, Emery did fairly well last season because of Wengers system still being drilled into the players.
The main problem lies with Kroenke though.
You are 100% absolutely correct that Wenger is the best thing to happen for us, easily. However, just because he deserves a legacy and statue outside of the Emirates also doesn't mean there were dark chapters with him. I am sorry, but he stayed six years too long. I am also in agreement with you that his consistency to finish top 4 with super average squads is unbelievably impressive.
However, he was also responsible for the entire downfall at our club...
- The Invincibles squad was slowly torn apart due to Wenger's reluctance to sign older players to deals which would keep them a bit longer. Sure, there was a very decent chance of them declining, but the greatest squad ever assembled was eventually sold and replaced by the rubbish you mentioned above such as Djourou, Squillaci, Chamakh, Bendtner, Santos, and others.
- Champion's League results is another aspect which he was a failure in the second part of his career at Arsenal. He made the finals just once and though it was terrible luck to lose the way we did to Barca, one appearance in the finals is pretty pathetic considering the squad we had. Additionally, as I mentioned about the second half of his career at Arsenal had some of the worst CL upsets and matches against us. 10-2 on aggregate against Bayern Munich, beat by Barca in 08/09, beat by Barca in 09/10 (R16), beat by AC Milan in 10/11 (R16) , beat by Bayern (R16) 11/12, beat by Bayern 12/13 (R16), beat by Bayern 13/14 (R16), beat by effin' Monaco 14/15 (R16), beat by Barca 15/16 (R16), beat by Atletico 16/17 (QF), and didn't make it after that. Sure we got spanked around by Bayern's gold generation squad, but we kept drawing ****ing Bayern and Barcelona every year because we kept finishing second in group stages against pathetic opponents.
- His arrogance on the squad is probably the biggest, people can blame Kroenke for being cheap, but honestly Wenger was the real realise why we spent so little. He never spent a lot like ever, even during our gold generation team he kept finding hidden gems and eventually hit jackpots more often than not. However, when The Invincibles squad was slowly deconstructed and sold to the likes of everywhere they were replaced by Wenger's next generation of gems which you wrote above in Bendtner, Chamakh, Djourou, Senderos, Gervinho, Andre Santos, Squillaci, Arshavin, Diaby, Vermaelen, Sagna, Clichy, Gibbs, Walcott, van Persie, Fabregas, and Rosicky. Don't get me wrong there's some good players in there, but more trash than treasure.
He trusted his players too much and made him blind from the real issue at hand and that is they were simply not good enough. Not good enough and why we kept getting destroyed by the likes of 2nd place group stage, Bayern, and Barca every year on repeat. Insanity is the doing the same thing and expecting a different result...well, doesn't that explain the lack of success in the CL quite nicely? Considering how many times we played both teams, you'd think we could squeeze out one upset, but no and we got beat by the same weaknesses every year...send too many players forward, get beat on the counterattack (definition of insanity x2). His record against the top 6 in the last decade was also beyond terrible, getting wrecked consistently was just terrible to watch.
- In the end, he needed to leave. This team at the time needed a change in direction and fresh outlook because his tactics were behind the times. He's still a legend to me, but I am also not blind enough to see that he created the dark chapters of his footballing legacy by staying so long. It's Arsenal FC, not Arsene FC. No other manager in any major sport had the same job security as he had, it was insane if you think about it. Nothing changed for twenty years and when you're on the downside making terrible moves after another you eventually find yourself with the squad we have now.
Think about it, the worst players currently at Arsenal are ones that he bought under his regime such as Mustafi, Xhaka, Kolasinac, Ozil, Elneny, and perhaps Mkhi, but not going to say 100% because it seems he wanted Martial while Sven got his Auba/Mkhi partnership from Dortmund. Additionally, the youth academy was in absolutely dire shape during his final five seasons as well. Unbelievably bad and another wanker is Ivan Gazidis, hope he rots and never joins another football programme after he gets fired from AC Milan.
I understand the lads who say we should've never fired Arsene for the likes of Emery, Freddie, and what has happened to our club now. But I am not on that train; he needed to leave and this club needed a fresh outlook. Sometimes you miss with the likes of Emery, happens to every club, but I also think this current dark period is just a little blip in a bigger picture. The new manager will not produce the same terrible record that is bestowing the club currently with Ljungberg, we just have to wait until the new one gets hired.
We probably don't make the top 5 this year, should get demolished the further we go in the Europa, and comments of firing Emery without a replacement are warranted. However, not winning a game since like early November is more fluke than anything to me. Arsenal's squad is good enough to be able to beat teams like Standard Liege, Brighton, Soton, Norwich, and others. I don't think Kroenke is the problem, he pretty much gives funds and allows the club to function...he is very hands off owner. The problem though, is that him living in America reduces the ability to fully understand the front office and squad's problems and that he's definitely naive in how sports function in Europe. That doesn't mean he is the worst owner though.
