The Posh under 18s are top of the table after an emphatic 3-0 win over Gillingham.
The Peterborough United under 18s are now top of the table and into the second round of the Youth Alliance Cup after another excellent weekend at the Nene Park Academy.
The Posh youngsters beat Gillingham 3-0 despite fielding three trialists in midfield and losing the services of Harry Anderson to the first team group.
Robertson has been pleased with his side's start to the campaign, but is not getting carried away.
'I was really pleased with the performance. We had a number of trialists involved as well as four under 16s on the bench, two of which managed to get some playing time. We kept our discipline and arguably in the first half we should have been more than two goals to the good.
'We did some work with Tye during the week about his runs and his movement patterns and to be fair he identified the spaces and took his goals very well. He was very composed with the first goal taking it around the keeper and he finished the second goal very well.
'We had two first year-scholars on trial involved and also a second year scholar and with Harry Anderson involved with the first team it gave us an opportunity to take a look at them. We have had a good August, but we are no getting carried away. Nobody wins a league in August and we need to keep it going,' Robertson said.
Posh: Henry, Luto, Marshall, Palmer, Ward, Hood, Trialist A, Trialist B, Trialist C, Friend, Phillips.
