Some were successful in earning Fratton Park deals – with Kieron Freeman, Jayden Reid, Gassan Ahadme and Louis Thompson all offered extended stays.
Yet many were shown the door as the Blues head coach decided against calling on their services further.
We’ll never know exactly how many were asked to attend the club’s Roko training base given Pompey’s wish not to name them all.
But here’s 14 who came and went after being deemed not good enough.
