The under 18s were beaten 2-0 by Luton Town at the weekend.
The Peterborough United under 18s were beaten 2-0 by Luton Town on Saturday, but Academy Manager Dave Robertson was pleased with a number of individual performances against the Hattters.
Goalkeeper Alex Lynch and striker Ty Phillips were both in excellent form, but goals in the second half condemned the Posh side to defeat.
Posh had chances to score, particularly through Dan Lawlor and Levi Wright, but failed to convert and Robertson admits that complacency may have been an issue.
'In our first three games, we had won two and drawn one so we went into the fixture with non-league opposition in good form. We started the game slowly and Luton were definitely at it and showed a great desire and willingness to press us high up the pitch.
'After a goalless first half, we spoke at the break about getting on the ball and passing it better, unfortunately poor defending allowed Luton to take the lead and they added to that in the final few minutes. I think complacency may have set in to our young players. We spoke to them after the game about that and it cannot happen again as our next fixtures against MK Dons and Watford will be a good test.
'I felt the distribution of our goalkeeper Alex Lynch was superb and under 16s striker Ty Phillips held the ball up and was a real threat when he came on for the last 20 minutes of the game.'
Posh: Lynch, Butt (sub Carter), Sage, Hendry, Burgess, Anderson, Lawlor, Wood, Coulson, Sparrow (sub Carthy), Wright (sub Phillips).
