It's more that we have played ruinous football the past five years than we aren't suited for the 4-3-1-2. We are surely not suited for the straight 4-4-2 anymore, so what else would we play? We've been kicking the can and playing crap football for years now, so of course it will be tough to break out of the same old long ball Cap Crap. Ranieri just prolonged it.
In that case, there is still some way to go, since we are mostly drawing and Buffon is doing is all to prevent Ciros wish?! But secretly Ciro has a plan, bringing Italian NT doctors in to this, with the Buffon knee operation barbadossa plan.
