Portsmouth 2025 summer transfers: Every confirmed signing and sale for John Mousinho's side

Portsmouth supporters went into the 2024-25 Championship campaign with low expectations after their promotion, but alarm bells were ringing when they failed to win a single game before matchday 10.

However, Pompey stuck by head coach John Mousinho and were rewarded for their faith when he guided the team to safety, securing another season in the division with a 16th-placed finish.

Portsmouth will be looking to build upon their work from last season, and they fancy their chances of doing just that after enjoying a productive transfer window. 

Pompey made 11 new additions to their squad during the summer market, including the deadline-day arrivals of Josef Bursik, Makenzie Kirk and Franco Umeh-Chibueze.

Portsmouth saved the best for last by announcing the return of academy product Conor Chaplin on a season-long loan deal from Ipswich Town.

With the window completed, Mousinho's squad will now be looking towards the South Coast derby against rivals Southampton on September 14.

Here, Sports Mole follows every arrival and departure from Portsmouth in the 2025 summer transfer window.
