As a unit, our patterns of play are complexed, intricate and finely tuned but McKenna makes it very simple for the players and concentrates on what they can do, rather than what they can't do. Every player knows their role and knows where they need to be if the ball is in 'position X' or position Y'. If Davis has that ball in behind, wide left you can bet Hirst/Broadhead are sucking the defenders into the box with Chaplin holding his position waiting for the pull back.
I think you might be surprised what Manning can get out of some of the players. I am sure you have your Morsy/Burgess equivalents that can be transformed into totally different beasts.
