13. Mahlon Romeo (Cardiff)
Pompey: 41 games, 0 goalsHaving become a target for Millwall fans, Romeo dropped out of the Championship for a season-long loan at Fratton Park in 2021-22 under Danny Cowley. Enjoyed an excellent first half of the campaign, then noticeably tailed off, losing his right-back spot to Hayden Carter. He joined Cardiff permanently in the summer of 2022 for an undisclosed fee and last season totalled 18 appearances. Picture: Jason Brown/ProSportsImages Photo: Jason Brown
14. Kal Naismith (Bristol City)
Pompey: 94 games, 21 goalsPaul Cook paid a transfer fee for the Scottish winger to land him from Accrington in May 2015, yet within 12 months Naismith has been written off, transfer-listed and not handed a first-team number. However, he responded with a stunning second season to finish as 17-goal top scorer to inspire the Blues to the League Two title. Has since featured for Wigan, Luton and Bristol City. Made 15 appearances and scored twice this year in an injury-ravaged campaign. Picture: Joe Pepler Photo: Joe Pepler
15. Matt Clarke (Middlesbrough)
Pompey: 175 games, nine goalsInitially recruited on a season-long loan from Ipswich in the summer of 2015, that classy centre-half joined permanently at the end of the season as part of the deal which took Adam Webster to Portman Road. Ended up staying at Fratton Park for four years, being awarded The News/Sports Mail Player Of The Season for 2017-18 and 2018-19 before sold to Brighton for £3.4m in June 2019. He later spent successful loan spells at Derby (twice) and West Brom, before joining Middlesbrough in August 2022. Picture: Joe Pepler Photo: Joe Pepler
16. Jamal Lowe
Pompey: 119 games, 29 goalsRecruited from Hampton & Richmond in October 2016, Lowe went on to feature in Pompey teams which won the League Two title and the Checkatrade Trophy. A direct winger with a brilliant eye for goal, he left for Wigan in the summer of 2019 in a deal worth around £2.5m. Went on to play for Bournemouth in the Premier League, but has since been sent on loans to QPR and Swansea. A free agent this summer, he will be looking at the Championship as a home after nine goals in 35 matches with Swansea this season. Picture: Joe Pepler Photo: Joe Pepler
