Its not just our system that matters though.
There is an increasing trend for the very high press in the Championship and the success of 'cheaper' teams such as Leeds and Pigs and to a lesser extent Norwich will mean this only increases. This style basically stops a team playing out from the back unless they are exceptionally brave at the back and earn the right to play. In that scenario any team has to lump it long from the keeper a lot of the time and you need a Fletcher type to compete and win the header. Bruce has shown that we are going to do this to other teams at times too at times, so there has to be a lot of energy in the front players to chase down. Midfielders have to play higher up the pitch and be more mobile than we have been for a couple of seasons. No more sitting back.
First season under CC high proportion of our goals were through us 'trapping' defenders or midfield players in possession about 40 yards from goal and getting the break from the mistake. FF was brilliant at it. Everybody is wise to that now. Things move on. Our new players will reflect this.
