The Posh under 18s recorded a 4-3 victory over Stevenage on the opening day of the season.
Jack Collison's under 18s secured a thrilling 4-3 success over Stevenage at the Mick George Training Academy in their opening league fixture of the season.
An enthralling encounter was settled by a penalty five minutes from time by Hugh Alban-Jones after Deon Moore was felled in the area.
Morgan Penfold rounded off a superb team move for the first Posh goal with Cameron Stump continuing his pre-season goalscoring form by converting an excellent Alban-Jones pass.
Moore rounded the Stevenage keeper to give Posh a 3-2 lead early in the second half, but after a sustained spell of pressure, the visitors equalised.
Posh secured all three points when Alban-Jones coolly converted from the spot after Moore had been fouled inside the box.
Collison was pleased with aspects of his side's performance, but admits there are things to work on: "Goals, goals and more goals is the simple description of the game! I thought we played well in the first half, but we gave two very sloppy goals away and only had two goals to show for our efforts ourselves.
"I was pleased to see Cameron get himself on the score-sheet. He has been in fine form in pre-season, so it was great to see him take that into the league campaign.
"There are lots of positives to take, I set the players a target for the first eight games of the season (seven league games and one cup-tie), so to start with a win was pleasing.
"We played some good stuff in patches, but there are loads of improvements we can make and the lads will be working hard to make those moving forward," Collison said.
Posh: Elsom, Freestone, Cartwright, Connor, Noble (sub Ferrier 60min), Alban-Jones, Baldry, Gow (sub Maddison 46min), Penfold, Stump (sub Douglas 70min), Moore.
