If Benitez brings stability and constantly challenges for Europe then there'll not be one blue carrying an agenda against him or calling for his head, the whole narrative of "he's only 2 bad results away from fans turning on him" is nonsense really but that doesn't mean he won't get criticism when he deserves it. If he gets us top 8 this year, given what we've spent and the poor depth in the squad, he should be commended. However he still has a long way to go to convince many that he's a long term (2 years+) solution for us.
Him keeping us "out of danger" isn't good enough quite frankly, he must compete. That is what we should expect of any manager. For god sake Big Sam got us in the top 8, that is the absolute minimum for us. If he achieves that great but what people are afraid of is if he doesn't we'd have literally tried every type of manager and failed every single time. Rafael has to bring stability like I said but I brought up Big Sam for a reason, he got top 8, Rafael should too but sometimes that simply isn't good enough, seasons like this where Spurs, Arsenal and Leicester and all on the down seemingly there's a real chance for us to break into 5th and be part of the Champions League conversation like Leicester did last season.
We always miss out on these opportunities of other teams being crap by being crap ourselves, it really isn't that hard to be a top 7 team anymore which is almost always Europe, Chelsea, City and Liverpool are guarantees for CL and United probably are now too, outside of that there's nothing special about the rest of the league at all. So like I was saying if we don't challenge for full Europa League qualification this year then it'll not only be a massive disappointment and missed opportunity but it might also be a sign of Benitez not being the best candidate for us, unless we get wrecked by injuries and get no one in January, even with that top 8 is mandatory.
