And do they conclude that managers don't make a difference? Of course they don't. To quote:

"The manager is far from an irrelevance. Yes fortune is of huge significance in football. It accounts for around half of what we see on the pitch and in the final league table. Yes, money is a factor. But there is much more to this game, to the pursuit of the goal. There is a world of styles to choose from, a huge amount of factors to consider, and the very best generals will use all of the information they have to get the best out of the resources at their disposal. They will think laterally and innovatively, and they will find ways of changing the game for their own benefit. They do have an impact."
