I do love the use of sarcasm. Unfortunately sarcasm doesn't work here, because the exact thing you are warning against (relegation) is basically what Martinez has achieved.
Even Stubbs has never been relegated, martinez has. And before people start, his budget is not far off Evertons (when you compare the sizes of the clubs in the top 5/6). His squad and budget was a lot stronger than the one Moyes inherited. Yet Moyes turned us into a regular top 5 side, in the same time Martinez has taken Wigan down.
It's also fine throwing names like Joe Royle about. But the club is in a different situation now to 94. In 94 we were on the brink of relegation, stranded at the bottom. We could have taken anyone. We are now a regular top 6 team. Our sites should be a lt higher.
The point about internal candidates is that, they can't be as bad as Martinez. I want us to get a top European coach in. Winning the FA cup is an irrelevence compared to ensuring league performance is adaquate (ie survival). Just look at Portsmouth.
