The pair are expected to be in the Posh squad when they head to Leyton Orient for a League One fixture in Saturday. Aderoju was signed from Biggleswade United and Kamara moved to London Road from Welling.
Kyrell Lisbie and defender George Nevett, who joined Posh from Rochdale, should also be in that matchday squad at Brisbane Road. Lisbie has been outstanding since coming into the Football League from National League Braintree last summer. Chris Conn-Clarke has been far less successful since arriving from Altrincham in June, 2024.
Posh have had great success in the past with players who arrived from non-league football, notably the ‘Holy Trinity' of Craig-Mackail-Smith, George Boyd and Aaron Mclean in the early days of Darragh MacAnthony’s ownership.
But what’s the Posh success rate been like in more recent seasons? We’ve looked at the last 20 Posh signings from non-league – excluding current players – and rated them as hits or misses.
