This is a horribly misguided post.
Wenger is not a specialist in failure by any means - his sixteen trophies say otherwise. Admittedly, he's had a trophy drought at Arsenal in recent years, but it's not like he's spent lavishly without any success, or that they've missed out on Champions League football. Mourinho's success is down to the resources he's had at his disposal as much as his managerial talent, since he's managed at clubs who had either a good squad, or a lot of money.
Regarding Mart?nez, there's no doubt he's done a good job at Everton so far, but it's been with a squad largely built by Moyes and with the somewhat lucky addition of Lukaku. And anyway, they're not in the European spots, which is where Everton often were under Moyes, so that point is basically invalid.
Essentially, what I'm trying to say is, the examples you've used don't really prove your point that well, since Wenger is definitely not a specialist in failure and Mart?nez hasn't eclipsed the achievements of Moyes.
