Yes, Posh did change formations against Leyton Orient by playing the diamond but that was a decision that did not bear fruit.
Yet, there is a formation that Posh have used to great effect from the start this season and that is the three at the back, which the Peterborough Telegraph believes gets the best out of young loanees Jadel Katongo and Zak Sturge.
Therefore, the PT suggests a switch to the 3-4-1-2 when Posh face goalless Cheltenham Town on Tuesday.

2. ZAK STURGE
Sturge looks to be a real athlete, able to provide more attacking impetus and someone who is also less likely to be exposed when asked to defend than Harrison Burrows. Photo: Joe Dent
3. RONNIE EDWARDS
He is Posh's best centre-back and best option to play on the left after a couple of recent disappointing displays from Romoney Crichlow. Photo: Pete Norton
4. JADEL KATONGO
Even in his one appearance so far, his Manchester City pedigree is obvious. Both him and Edwards should have no problem starting the Posh attacks from the back. Photo: Joe Dent
