Posh have won 17 and lost seven of the 28 clashes. They haven’t lost one since a 1-0 reverse in April, 2006 when ex-Posh striker Scott McGleish scored the only goal early in a League One game following a mistake by Sean St Ledger.
Posh have also won 12 and lost seven of the 28 away games so plenty of club derby day heroes for us to recall here...
