# Mahdi Nicoll-Jazuli becomes Chelsea’s youngest Premier League player

Chelsea’s academy has produced another record breaker. This September 2026 update confirms Mahdi Nicoll-Jazuli is now Chelsea’s youngest PL player after his first-team debut against Brentford. The 16-year-old has moved from youth football to a Premier League matchday squad in a matter of months.

Here is how he got there, what happened at the Gtech Community Stadium, and what comes next.

## Mahdi Nicoll-Jazuli Makes History in September 2026 Update

Nicoll-Jazuli’s name entered the record books this month. Xabi Alonso brought him on late in a Premier League away game. That made him the youngest player to appear for Chelsea since the competition began.

The match did not go Chelsea’s way. Jaidon Anthony and Igor Thiago put Brentford 2-0 up, and Fábio Carvalho added a third in stoppage time. The final score was 3-0. Even so, Nicoll-Jazuli’s introduction was the story fans took home from west London.

## Rising Through the Chelsea Youth Ranks

Nicoll-Jazuli’s rise through the academy has been fast. He already holds two youth records at Chelsea. He is the club’s youngest-ever starter in the UEFA Youth League, and the youngest-ever scorer in that competition too.

He has shown his talent outside youth football as well. In pre-season, he started against Juventus and played in midfield opposite Manuel Locatelli and Douglas Luiz, both experienced internationals. That display seems to have convinced Alonso to name him in a senior squad for the first time this season.

## Nicoll-Jazuli Becomes Chelsea Youngest PL Player Against Brentford

The answer to who is Chelsea’s youngest PL player is Mahdi Nicoll-Jazuli, who came on as a substitute against Brentford. He replaced [Pedro Neto](https://readchelsea.com/squad/pedro-neto/) in the 87th minute at the Gtech Community Stadium, aged just 16.

The game finished 3-0 to Brentford. Before kick-off, Nicoll-Jazuli had been named in a competitive first-team matchday squad for the first time in his career.

Alonso used his final substitution on the teenager, with the result already decided. That gave Nicoll-Jazuli his moment, in a game covered in detail in our [original report on Nicoll-Jazuli](https://readchelsea.com/2026/09/18/mahdi-nicoll-jazuli-chelsea-youngest-premier-league-player/).

## What Happens Next for the 16-Year-Old

There is no confirmed word yet on when Nicoll-Jazuli will next feature for the first team. His inclusion in the squad against Brentford shows he is part of Alonso’s plans. Nothing has been said publicly about a starting role or a longer run in the side.

How he is used from here will likely depend on [Xabi Alonso’s tactical setup at Chelsea](https://readchelsea.com/2026/06/27/chelsea-badge-refresh-xabi-alonso-brand-test/) and the form of the midfielders ahead of him. If his progress continues, he could one day be mentioned alongside some of the [top Chelsea Premier League performers](https://readchelsea.com/2023/01/03/best-chelsea-strikers-in-the-premier-league-era/) to come through the club’s ranks. For now, his cameo against Brentford marks the start of a career that began earlier than almost anyone else’s at Stamford Bridge.
