I would name the following side, we are depleted and I think we need to be solid down the middle as I fully expect Peterborough to put us under extreme pressure.
I would name a 4-5-1 formation with Kisnorbo playing just in front of Hobbs and Morrison to provide additional support, this will allow Oakley to be freed up more and get on the ball and dictate play when we are in possession. I also think this formation and the addition of Kisnorbo will provide more aerial support in both penalty areas. It will also encourage us to get the ball down, play football and use the threat of Gradel and Dyer to hit Peterborough on the break. The five in midfield will also allow us to get on top of them and stop them from playing. IMO Fryatt is capable of playing with his back to goal and if we can get the ball into his feet then he will be able to bring the supporting Oakley, Gradel and Dyer into play. This will stop the aimless hoof and IMO give us the best possible opportunity of fustrating and stifling them.
My line up would be
Stockdale or Warner
Gilbert
Hobbs
Morrison
Powell
Kisnorbo
Gradel
Berner
Oakley
Dyer
Fryatt
Subs
Warner or Stockdale
Mattock
Adams
Dickov
Hayles
