Arsene is a legend. Arguably the second best manager of the Premier League era. But it was past his time. He didn't have it anymore. The excuse in his defense for mediocrity the handful of season when Chelsea, United, and City dominated the top was that they weren't spending money to pay for Emirates. But they're spending money now. Arsenal's wage bill is a lot closer to United and City than it is to Liverpool, the next team below them.
It's clear that Arsene is a legend of a former era. But he's outclassed now by guys like Pep, Poch, and Klopp. Not to mention Jose is still better.
Klopp has bested him since coming to Pool. But he's played really good tactical matches against Pep and Poch the last few years. The FA Cup Semi against City last year was proof of that. As I said, the record is a lot worse than the team has played.
The home loss to United, the away draw at Chelsea this year. We actually pushed City at Etihad very tough for most of the game before the offside non-calls. All of those matches we had terrible luck despite outplaying the other sides.
Its dumb to say Wenger is being "outclassed" by those guys when its not true and it's even dumber because there isn't anyone right now to step in his shoes and do better. The Premier League has gotten just that tough. Wenger is still an elite world class manager. Ownership though is still a big issue.
