I certainly don't think Elano is blameless, and I agree that he hasn't been firing on all cylinders since last Christmas.
But he has still been extremely useful for us in that time (those stats surprised me a bit, and show just how significant he was to a team doing so much better than we currently are),. He's also been a whole lot better than others that seem to escape criticism or "get rid" talk. He spent a lot of time in the past 12 months playing as a deep lying midfielder, and I just don't think that we'll ever get the best of him in that role.
He strikes me as a petulant type, and one that needs to be mollycoddled a fair bit. But if the right manager found the buttons to press, I think we could have a player on our hands thats even better than what we saw in the early part of the season.
He probably is a managers worst nightmare, but the best managers can also see those types as a great opportunity.
