Just as a starting point, I don’t think we should be changing our formation!
Now, given we have another game three days after Peterborough on Saturday, I think we need to be clever with the team selection. Players who played the full game against Newcastle, including extra time, probably should be rested on Saturday wherever possible, and then brought back in on Tuesday, so basically a week break for them. Therefore, depending on injuries etc (How fit is Browne? Henry?) I’d make two teams, A) for Peterborough and then B) for Burton.
A) Sat against Peterborough:
Eastwood
Long Dickie Mousinho Ruffels
Gorrin
Henry Thorne/Kelly
Agyei Mackie Browne
Maybe Hanson for Long if he’s knackered. Whichever one of Thorne or Kelly is fitter. And only Henry or Browne if they’re fully fit, and even then aim to give them 60-75 mins. Don’t risk Brannigan or Taylor yet, keep sensibly managing them back.
B) Tuesday against Burton:
Eastwood
Long Dickie Moore Ruffels
Thorne/Kelly
Sykes Brannigan
Holland Taylor Browne
Bring back in Brannigan, Taylor, Sykes and Holland now they’ve had a week to recover. Assuming Browne didn’t play 90 mins on Sat then keep him in the team. Maybe rest Gorrin, and maybe bring Hanson in for Long.
