You have to ask yourself, Dita, what is expected of Wenger by the Arsenal bosses? According to outsiders, Arsenal should be winning the league, but what if they're quite happy with him getting them to the CL K.O. stages every season? I don't think any manager in the league should be expected to win the league but Roberto Mancini. When you're the highest spenders both on transfers and wages, then you're clearly at a significant advantage over everybody else. Wenger clearly works within budgets and restraints, if he didn't, he would've been able to keep Flamini all those years ago, he would have been chucking big contracts out to players like Nasri and Clichy before they ran them down. For me, there should be more questions asked of Wenger's board and Arsenal's ownership, if they want to win the league and they want silverware, they'll have to cough up every bit of profit they get every summer, but that won't happen.
Similarly, Everton fans may be frustrated with Moyes, I can see why in ways, but maybe they're expecting too much from a manager that has consistently overachieved? Maybe Moyes' tactics are overly negative, maybe he is holding the squad back, but has he not earned the chance to maybe ride out the bad period and try to start afresh? Me personally, I've read a fair amount on Moyes and he seems a decent manager, certainly not your typical British manager, but maybe Evertonians disagree. If you look through some of his signings, there's no doubting he's done well on the budgets, maybe if they can get budgets like that again (selling Rodwell and possibly Barkley?) he can get Everton back up to the top 8? I dunno, I just think it's very hard to judge a manager who's clearly been restricted by those above him.
