Out of the seven who arrived at Fratton Park last season, perhaps only Miguel Azeez, Gassan Ahadme and Tyler Walker didn’t live up to expectations.
However, Gavin Bazunu, Hayden Carter and George Hirst left a lasting impression in royal blue, while Mahlon Romeo’s form dipped after an electric start to life on the south coast.
As a result, Danny Cowley will be searching for replacements for those who are set to return to their parent club.
He hasn’t given up hope on bringing the Blackburn and Leicester figures back to the club – but if his pursuit returns empty who could he look to sign?
Here’s who had similar seasons to the Blues’ loan contingent using WhoScored.com’s stats.
9. Daniel Udoh - Shrewsbury
Udoh scored 16 goals in all competitions last season for a Shrewsbury side that blew hot and cold. After three seasons at the club, the 25-year-old may be seeking pastures new - but would command a transfer fee. Picture: PAUL ELLIS/AFP via Getty Images Photo: PAUL ELLIS
10. Troy Parrott - Spurs
Parrott was expected to light up the division last term on loan with MK Dons, but couldn't quite live up to the hype. The Spurs striker scored nine league goals for Liam Manning's side which suggests another loan to the third tier would benefit him before stepping into the Championship or the Premier League.
