Just throwing this out there: I see from the official site that Didi Hamann is taking his coaching badges and wouldn't mind getting back to Liverpool in that capacity. What do you think about him and Carra together as manager and assistant (not necessarily in that order) for LFC some years down the line? Obviously they'd both be wet behind the ears in that capacity if Liverpool was their first club from a managerial perspective, but I'm talking about after they've gained some experience.
I think Carra has the knowledge, class, and mouth to pull it off. He claims he might lose his temper at the team on occasion, and well, I'd hate to be a guilty party in the change room on that day!
