Didn't they say the post was not for a 'novice'? Not to be unfair to Clark, but in managerial terms he still is pretty green. Even with their first shortlist seemingly unavailable, doubt they'd renege on such a bold statement, so soon - more out of pride than anything else!
Ah yeah, so they did. True, Clark still isn't quite there yet.
Not sure who Wolves will bring in now really, especially now that their first choices have seemingly turned them down. Your suggestion of Sven might be a good shout actually, hmmm.
