The 21-year-old winger, who joined Brighton on a free transfer from Arsenal in 2024, spent the 2025-26 season on loan at Bolton, where he recorded nine goals and 13 assists in 37 League One appearances. His form helped Bolton secure promotion to the Championship via the play-offs and earned him nominations for both the EFL and PFA Player of the Season awards, alongside a place in the division's Team of the Season.
With two years remaining on his Brighton contract, which runs until 2028, discussions over his long-term future have already begun. According to Fabrizio Romano, Brighton have proposed a new contract, though the situation remains what Romano described as an "open race," with clubs from Germany and France also showing interest.
Several outcomes remain on the table. Cozier-Duberry could sign a new deal and remain at the Amex Stadium, stay under his current terms, or depart on a permanent transfer — though sources stress it remains early in the process.
Brighton's involvement in next season's UEFA Conference League is expected to create more first-team opportunities across the squad, which could allow Cozier-Duberry to take on a cup-competition role while featuring as an impact substitute in the Premier League — a pathway that would not require an immediate permanent departure.
Yet the possibility of a permanent exit remains live. His performances at Bolton — recovering from a knee ligament injury that cost him 12 league matches earlier in the campaign — have attracted interest from clubs in England and abroad, with German and French sides specifically mentioned as having made contact.
Cozier-Duberry's path to this point has not been straightforward. After impressing on a pre-season tour of Japan with Brighton, a difficult loan spell at Blackburn Rovers in the Championship preceded his drop down to League One with Bolton — where, under manager Steven Schumacher, his game has flourished. He scored Bolton's decisive goal in the first leg of their play-off semi-final against Bradford City, curling a finish beyond goalkeeper Sam Walker after cutting in from the right.
Brighton's sporting director Jason Ayto, who previously worked within Arsenal's academy setup, is understood to know the player well from that earlier spell and has taken a close personal interest in his development.
For a 21-year-old who has already experienced loans at three different clubs in three years, this summer represents the moment his career path gets decided — by Brighton, by suitors, or, increasingly, by himself.
