And I think they will be unhappy for a long time. There is so much wrong at Arsenal and its not going to be fixed with a few players or a new manager.
When Wenger took over he was challenging against Fergusons United team and his attacking play, solid defence and ideas about diet and training won him the league. Arsenal fell behind when they developed the Emirates and United splashed the cash and Abramovich used his oil money to financially dope Chelsea into the top levels of English and European football.
Now they appear to be willing to spend more money on players, but the legacy of Wengers absolute control of the football side and Dein leaving is a club that is miles behind Liverpool and City as an organisation designed to win trophies.
I still dont think its a massive overhaul that Arsenal need. They've lost their way, they've lost confidence in what's happening right now, & in the manager. But there's still a decent base of players there for any new manager to work with. This is by in large a squad that was 1 point off top 4 6 months ago. Leno, Tierney, Bellerin, Geundouzi, Torriera, Aubameyang, Lacazette, Pepe, more youngsters coming through like Martinelli, Saka, Willock, Nelson, Saliba to arrive in 6 months....you can't tell me most managers wouldn't like to have those options available to them?
The squad's still in imbalanced though, lacking pace & power in midfield & central defence, lacking defensive nous, structure & organisation. I'm not naive enough to think there's not a lot of work to do, buy you can't tell me however that most managers worth their salt wouldn't fancy a crack at the job. That they can improve on what we are seeing right now.
As for the structure behind the manager, it's too early to judge the new regime. This is Sanllehi's first full year in his new role, Edu only arrived after the Copa America in the summer, so they need to be given time. This was never going to be a quick fix, & at least in their dealings in the summer etc they show they are thinking about the long term. I don't think they expected this short term pain though in the meantime.
