Weirdly, I think this is Lambert wanting to play a better style of football.
I think he wants players in the backroom and on the pitch who played with him at Norwich, so he can help make us transition from quick counter attack only to playing in a style more reminiscent of his Norwich. Plus, if you're going to sign a player for an off the field impact (and I subscribe to Carregher and Neville's theories that this is why he was brought in), it's not a bad shout signing one you know well.
