Cozier-Duberry scored eight goals for Bolton Wanderers last season, helping them win promotion from League One, and returned to Brighton having demonstrated he can perform consistently at senior level.
However, Brighton have since agreed to sign winger Zadok Yohanna from AIK Stockholm in a deal worth £21.5m, a move that is likely to further restrict Cozier-Duberry's path into the first team.
According to The Sun, Hull and Leeds are among the clubs watching his situation. Hull, who won promotion to the Premier League last season, are looking to add wide options as they prepare for top-flight football. Leeds are open to bringing in another winger, particularly if Wilfried Gnonto departs.
West Ham United are also keeping tabs on the youngster, as are French sides Paris FC and Strasbourg, along with Bundesliga club Freiburg. The level of interest reflects the impression Cozier-Duberry made during his time at Bolton, even if a path to regular first-team football at Brighton now looks difficult.
A loan or permanent exit this summer appears the most likely outcome as Cozier-Duberry and his representatives weigh the options available.
For Cozier-Duberry, the priority is finding a club where he can build on the form that made him one of League One's more dynamic wide players last season. A Premier League move with Hull or Leeds — where he would face genuine competition but also the opportunity to develop against top-level opposition — represent a very different trajectory for the 21-year-old as he enters a summer that will shape the next phase of his career.
