Carsley Explains Cozier-Duberry Call-Up Following Middlesbrough Form
The Amario Cozier-Duberry England U21 call-up has finally arrived, and Lee Carsley has explained exactly why it took this long. The Brighton loanee is now with the Young Lions, working towards Saturday’s fixture against Kazakhstan at Molineux.
Carsley made clear the delay was never a question of ability. He said Cozier-Duberry deserves to be part of his squad for the Euros qualifiers, but timing mattered as much as talent.
The winger has forced his way in through form rather than reputation. On a season-long loan at Middlesbrough, he has scored in back-to-back home games against Norwich City and Millwall, adding weight to a new contract he recently signed with Brighton & Hove Albion.
Lee Carsley Transcript & Dissection on Brighton Loanee Pathway
Speaking about Cozier-Duberry’s path into the squad, Carsley set out the thinking behind waiting for the right moment, as detailed in The Argus report.
“I think he started really well (at Middlesbrough). I think he had a good season last season also. It was a bit of a challenge calling him up (at Bolton) because of the number of players that they would have needed to be in internationals to get the game cancelled. So it was always getting the balance right between him coming away and maybe potentially not playing, but then missing games and then struggling to get back into the team. We’ve tried to get that balance right. Having a conversation with him that now he’s in a position where he can compete. It’s a very difficult squad to get in, especially in wider areas. He more than deserves this call-up that he’s got. With his contributions for Middlesbrough so far, and he’s an exciting player.”
That quote does a lot of work. Carsley is admitting the England set-up weighed the value of a call-up against the risk of Cozier-Duberry losing his rhythm at club level during his time at Bolton. Wide areas are congested in this England Under-21 group. A fringe role away from home was judged not worth the disruption.
Carsley also spoke about what he has seen from Cozier-Duberry in training with the squad.
“You see that in training. He’s very capable of taking the ball. He’s sharp. He can score a goal. He can create. We’re happy with him.”
It is a short, direct assessment, but it lines up with the goals he has produced for Middlesbrough. Carsley is not describing potential here. He is describing a player already delivering.
Middlesbrough and Brighton Context on Cozier-Duberry Progress
Cozier-Duberry’s route to this call-up runs through two loan spells. Last season he was out at Bolton Wanderers. Building minutes in League One while Carsley kept tabs on him. This season Brighton sent him to Middlesbrough on a season-long deal. A step up in level designed to test him against Championship defenders.
He has answered that test quickly. Goals in consecutive home fixtures against Norwich City and Millwall have made him a regular topic among Boro supporters, and they arrived not long after he put pen to paper on a new contract at Brighton. That deal signalled the club’s intention to keep developing him rather than let him drift as a squad player.
For Brighton fans, the pattern is a familiar one. Young players are sent out, monitored closely, and only brought into bigger conversations once form and fitness line up. Cozier-Duberry’s Middlesbrough form is exactly that alignment. It explains why Carsley felt comfortable finally making the call.
The wider point for Albion supporters is that this Amario Cozier-Duberry England U21 involvement is a product of sustained loan performances rather than a one-off selection. It reflects a player building a case match by match, at a level where mistakes are punished and form has to be earned.
International Duty Rules & Balancing Club Football Competition
Carsley’s explanation touches on a real constraint within the international calendar. Clubs are not obliged to release players for every underage fixture unless enough of their squad is required elsewhere to force a postponement of domestic games. At Bolton, that threshold was not met. This meant pulling Cozier-Duberry away risked disrupting his rhythm at League One level without an automatic route back into the side.
That is the balance Carsley referred to directly: bring a player away and risk him missing club games. Struggling to reclaim his place, or leave him to build consistency first. For a loan player trying to prove himself at a new club, continuity matters as much as the next step in his international career.
With Cozier-Duberry now established and scoring for Middlesbrough, That risk has eased. Carsley judged the moment right to bring him into a squad he has described as difficult to break into. Particularly in wide positions. The approach reflects a wider principle in England’s underage set-up. Call-ups are timed to protect a player’s club form, not simply to reward it as soon as it appears.
For now, the focus is Saturday’s qualifier against Kazakhstan at Molineux. Cozier-Duberry is in the squad on merit built entirely on the pitch at Middlesbrough.
