Well, being as though it was Culverhouse and Karsa that took the training sessions and some claiming they actually picked the team too, i would say it's pretty important. That's why people care.
Really? So what does Lambert actually do? Perhaps you will find the answer in the thread all about him, this isn't it.
Surely the question is relevant so we can determine what Keane's role will be if fans feel the previous assistants did so much?
Anyway whoever will end up being number 2 will be the best from a number of potential candidates surely. Best cv, interview etc.
