Why? Because unless you understand the history of the club you won't appreciate that the last 20 years or so have been the exception, not the rule. If you do thank Wenger for raising your expectations then you've got a funny way of showing it.
The stadium move would have had more impact had it not come in the era of billionaires muscling in. Leicester haven't popped anything, the billionaires HAVE had a massive effect over the the last decade or so. I don't need to argue that, just look at where the trophies ended up. This is a bizarre season, Leicester are a black swan (

Yes, Wenger needs to move on, I think he's taken us as far as he can. But "Thanks for the memories, Arsene, but it's time to say goodbye" is an appropriate tone, IMO, not some of the vitriol I see on here.
