I think this is the Crux of the matter, the new 'disco Stu' flair players haven't been allowed to go for it. They're not good enough for the CH plan of sitting deep and defending, because it's not what they've ever done before. So they appear to be failures.
We know CH ( very occaisionally)...
Neither the manager nor the 'new' players suit each other, that's patently obvious, and a big fail on the clubs part.
Half of the championship team/squad are marginal at best in the PL.
