JJ was a crazy appointment in my opinion. could have been good, but we need someone who is even more defensively minded (not Dutch Total Football related) and also has bags of experience (EPL please).
Kean is good at counter-attacking no doubt, but defensively he is weak. Allardyce and Coleman taught him nothing, clearly.
Ian Holloway would be ideal in my opinion and a hell of a lot more likely appointment than O'Neill. Holloway is rubbish with the media, he could benefit from a setup where Kean does all the namby pamby stuff while he gets stuck in behind the scenes.
