But for every Harrison Burrows there is a Flynn Clarke and for every Matthew Etherington there is a Janaai Gordon. Not every player goes on to fulfil their potential.
All the players featured here were Academy stars who made their Posh debuts at aged 18 or under. None of them made it at Football League level although one of them still has a chance and another scored twice in a World Cup qualifying game in the summer.
See how many you remember…
The players ages on debuts are listed as years/month/days.
9. GABE OVERTON
Age at debut: 17/5/24...Posh apps: 1...Current club: Lowestoft...Striker Overton came on as a late substitute in a 2-0 EFL Cup win at Plymouth Argyle in 2022.

10. FLYNN CLARKE
Age at debut: 17/8/17...Posh Apps: 11...Current club: Lowestoft...He looked a fine prospect when following a Posh debut as a substitute in an EFL Cup defeat at home to Cheltenham in 2020 with some decent EFL Trophy and League One appearances, which included a brilliant goal at Cambridge United, but he rejected a contract at Posh to join Norwich City and it's been a struggle since for the attacking midfielder, not helped by off-field issues. Also currently at Lowestoft, but sidelined by serious injury. Photo: Joe Dent
11. MORGAN PENFOLD
Age at debut: 17/8/27...Posh apps: 1...Future club: Wisbech Town...The striker's one Posh appearance was as a sub in that 6-1 home hammering at the hands of Norwich City in 2016. Did move to then National League side Barrow briefly before joining local non-league clubs Spalding United and Wisbech Town. Photo: Joe Dent
12. NATHAN KORANTENG
Age at debut: 17/9/1...Posh apps: 4...Current club: Waltham Abbey.. A powerful young winger was thrown in at the deep end with a debut as a second-half substitute in a 2010 Championship fixture at Swansea City by then Posh manager Jim Gannon. Koranteng started three games in the back of that relegation season, but never played again. Was at St Neots and St Albans and now at Waltham Abbey FC of the Isthmian League. Photo: David Lowndes
