Brighton transfer chief explains decision to let promising youngster join Middlesbrough

Middlesbrough have completed the signing of exciting Brighton forward Amario Cozier-Duberry on a season-long loan.

Cozier-Duberry has agreed a new contract until the summer of 2029 and will spend the season on loan with Middlesbrough, it has been confirmed.

Brighton’s sporting director Mike Cave said: “Amario had an excellent year with Bolton Wanderers last season and was one of the standout players in the league helping them to promotion. He’s had a very good pre-season with the first-team, that alongside his form last season meant there was significant interest in signing him on loan this season.

“That interest and his new contract is a reflection of his attitude, ability and hard work; now we look forward to watching him continue his progress in the Championship this season.”

The 21-year-old joined Brighton from Arsenal in July 2024, spending the season on loan with Blackburn Rovers, before joining Bolton last summer on loan.
