Posh complete their home league programme with a fixture against Crawley Town at the ABAX Stadium.
Peterborough United entertain struggling Crawley Town at the ABAX Stadium on Saturday (3pm) in the final home Sky Bet League One fixture of the campaign.
The Reds are battling the drop, but last weekend's 2-0 win over fellow strugglers Notts County has put the destiny in their own hands as they enter the final two fixtures of the season.
'I have asked permission from the school to allow Leo to train with the first team squad. Leo was unbelievable in the under 21 game this week, some of the things he did were incredible and he gives us another attacking option.
'I think he is a real talent. He is good enough, he is a confident lad and his temperament is not in question. The youth team have scored 92 goals in their games this year so there is plenty of goals in that group and Jonny Edwards came on for his debut last week.
'Our home form has been good since we came in. We wanted to make the ABAX Stadium a bit of a tough place to go and I think the players enjoy playing at the ground again and that is vitally important moving forward,' Robertson said.
The Posh boss confirmed that winger Jon Taylor's campaign is over. He has been struggling with a knee injury and the main focus is to get that right for the new campaign. 'We want Jon to report back on the 29th June and hit the ground running so he can be a big player for us next season.'
Striker Luke James does return to the squad after injury, but Kgosi Ntlhe is suspended and Jermaine Anderson and Jack Baldwin are long-term absentees.
There are a number of presentations taking place ahead of kick-off on Saturday including the BBC Radio Cambridgeshire Player of the Season award. There will also be a one-minute of silence as the Football League remembers those who lost their lives in the tragic Bradford fire disaster 30-years ago.
The players' will thank the supporters for their magnificent support following the game before the foreverposh end of season awards in the Posh Venue.
