Portsmouth have signed 17-year-old Arsenal defender Niamh Peacock on an Academy Development Registration deal. Betting outcome: her arrival boosts Portsmouth’s defensive options and could make a low-scoring finish more likely — punters may consider backing Portsmouth to keep a clean sheet or the match to finish under 2.5 goals if she starts against Durham.
Portsmouth complete signing of Arsenal defender Niamh Peacock
Portsmouth has completed the signing of 17-year-old Arsenal defender Niamh Peacock on an Academy Development Registration deal. Peacock becomes the first player to join Pompey under the new arrangement, marking a move designed to aid her transition from academy football to the senior game.

Academy Development Registration — what it means
The Academy Development Registration replaces the former dual-registration setup and allows young players to train and play in senior environments while remaining tied to their parent club. The arrangement is aimed at accelerating development by providing regular first-team exposure in competitive leagues.
Player background and recent experience
Peacock spent almost a decade progressing through the Arsenal academy and has represented the club at Professional Game Academy League level.
She gained senior minutes with Watford in the FA Women’s National League Southern Premier Division during the first half of the season and has represented England at youth levels up to Under-17.
Manager reaction
Portsmouth boss Jay Sadler said: “I’m pleased Niamh has joined the football club. She is a strong, ball-playing defender who’s gained valuable experience in a top environment at Arsenal. We knew we needed to strengthen defensively, and we appreciate Arsenal allowing us to play a role in the next phase of her development.”
Availability and upcoming fixture
Peacock could be included in Portsmouth’s squad for Sunday’s trip to Durham in Barclays WSL2, offering the manager an immediate defensive option ahead of a busy period.
Betting implications and market pointers
Her arrival should be viewed as a defensive reinforcement.
Punters might consider:
- Backing the match to finish under 2.5 goals if Peacock starts, reflecting increased defensive solidity.
- Considering Portsmouth to keep a clean sheet at shortened odds if lineups confirm her inclusion.
- Monitoring starting XI and team news before placing bets; defender signings typically have a greater impact on goals markets than outright match-winner markets.
