surely it's time to go all in on Arsenal??
You forget that American owners don't 'go all in' in the same way as people expect oligarchs and nation states to. Stans money didn't buy this championship, in fact he's going to be making huge amounts of money out of it in pretty much the opposite of what you're expectin him to do at Arsenal.
On the other hand this concept of young hungry coaches/managers being given the support to do theri thing with an equally young and hungry squad seems to be a hallmark, the only problem is that there is no US equivalent of Man City in the way.
