The thing I've noticed about top class managers is that when they join a new club, they don't go out all guns blazing from the start, they seem to spend the first few months working on the defensive side of the game and things like team shape. Then after a while, they let the players off the leash a bit and the team starts to play better and better football. My memory of Mark Hughes' early days was really exciting, attacking football, whereas I remember Mancini being a bit more cautious (maybe I'm misremembering though). The result was that Mark Hughes' defence was a shambles and never improved, whereas Mancini could start to play attractive football once everyone had been fully drilled in their basic defensive and positional responsibilities. I seem to remember Sven being the same, as well as Mourinho in his first stint as Chelsea manager. In other words, if we're still playing dull football in ten games time, then I'll start to worry.
